elan: Do not leak converted frames

The elan driver converts frames into a different format. These frames
are only needed to assemable the image and should be free'ed afterwards.

Fixes: #213

 This file lists notable changes in each release. For the full history of all
 changes, see ChangeLog.
 
-2019-11-20: v1.90.1 release
-
-This release fixes a lot of the regressions introduced in 1.90.0. Please note
-that both the driver and external APIs have changed, as both the verify and
-the identify functions now have early reporting mechanisms.
-The soname for the library, as well as a number of file locations have also
-changed. While this allows installation in parallel with the 1.0 version of
-libfprint, we recommend installing only one, and migrating from version 1.0 to
-version 2.0 alongside its main consumer (fprintd).
-
-Only major changes are listed below. A lot of other cleanup work and small
-fixes have also been merged.
-
-* Library:
-  - Add support to run tests in gdb/valgrind
-  - Allow testing on all architectures
-  - Avoid image device AWAIT_FINGER_ON to deactivate state transitions
-  - Fix verify/identify error propagation to library user
-  - Correctly read image device information from class data
-  - Continue enroll after an image driver reported a retry error
-  - Change external API to allow reporting match results early
-  - A lot of new unit tests and integration tests have been added
-
-* Drivers API
-  - Support variadic arguments in error functions
-  - Various re-definitions of ownership handling
-  - Add convenience API to change state after a timeout
-  - Add unit tests for all the drivers API
-
-* Drivers:
-  - elan: Ensure correct deactivation of device
-  - uru4000: Fix IRQ handler registration and internal state handling
-  - uru4000: Fix control transfer request type
-  - synaptics: Ensure errors are only reported after finger removal
-
 2019-11-20: v1.90.0 release
 
 This release updates the core of the library to use GLib routines and Gio

-Note that umockdev-record groups URBs aggressively. In most cases, manual
-intervention is unfortunately required. In most cases, drivers do a chain
-of commands like e.g. A then B each with a different reply. Umockdev will
-create a file like:
-
-A

-B
- reply 1
- reply 2

-which then needs to be re-ordered to be:

-B

-A
- reply 2
-B
- reply 2

-Other changes may be needed to get everything working. For example the elan
-driver relies on a timeout that is not reported correctly. In this case the
-driver works around it by interpreting the protocol error differently in
-the virtual environment.
