While useful, there are advantages for this to be done by the
surrounding code (i.e. fprintd). As such, remove the identify stage from
the goodix driver and rely on fprintd doing it for us.
One can probably argue that neither solution is perfect. Ideally, we
would probably return the information required to delete the old print
to the upper stack and let the driver/device handle the duplicate
checking.
However, for now this works well. We may need to reconsider this if we
get devices that do the duplicate checking transparently and just throw
an enroll error.
NOTE: The driver did not report any progress for the identify step. As
such, the number of enroll steps reported by the device remain the same.

It appears the kernel automatically "fixes" this mistake and it works.
the transfer in question is an interrupt transfer and should be submitted
as such. Do that in order to make things more correct and so that the
test can run.
Expose new versioned symbols that work with previous API so that we can
keep compatibility with old drivers without having to recompile them.
We disable the GCancellable API in delayed SSM actions since that was
something that wasn't really needed and prone to errors, instead of
just re-implementing it as it was in the TOD case.
Recompile tod drivers using libfprint-tod-test-drivers project [1] so
that we don't have to reorder the private driver structure, plus use a
versioned driver ID and parse it to check whether a feature is supported
for such TOD test driver.

This matches the expectation. i.e. we return no-match and we do not
return a scanned print as we don't have anything for it. If we did
indeed return a scanned print, then fprintd would try to delete it
during enroll and would then fail.
Note that we do *not* return a DATA_NOT_FOUND error in the storage
device if the print does not exist. This is because not all devices
support reporting this error. It is therefore more sensible to handle it
gracefully and expect test setups to set the error explicitly for
testing purposes.
The error may not be NULL, as such we need a second variable and then
we'll only forward any error from g_usb_device_release_interface if
there was none before.
