imgdev: Add fpi_imgdev_abort_scan() to abort scan gracefully from within the driver.

Browse source 
Smart sensors like Upek TouchChip Coprocessor can provide scan status instead
of image, as result we need to report such status as "short scan" or "finger not centered"
from within the driver, since it's not a session error.
