Vasily Khoruzhick 62818b9407 fpcmoc: fix use-after free in multiple callbacks 
Drop if statement that retrieves internal ssm->error.
"error" is already a copied ssm->error, so it makes no sense to return
internal copy which will be freed when ssm is marked as done.

Fixes #526

Vasily Khoruzhick 4cf5f92a52 lib: re-add partial image flag 
And activate perimeter points removal if this flag is set

This flag should be set for aes1610, aesx660, aes2501, aes2550
and upektc_img since these sensors may produce incomplete image.

Fixes: #142

during next update.

Smart sensors like Upek TouchChip Coprocessor can provide scan status instead

from within the driver, since it's not a session error.

hardware assistance will use software algorithm, which was also
improved to do search in horizontal direction.

The driver used to stop the scan immediately after an empty frame
(by checking for hist sum == 0), but it is possible to get empty
frames in the middle of the scan due to low finger pressure.
Waiting for 3 empty frames stop the driver wrongly aborting the scan
too early.
