New way of EIO error handling (v4l2src_call.c, rev 1.51) leads to loosing
buffers
(I mean buffers which are queued for grabbing frames) and as a result it leads
to
total application crash (when last buffer has been lost).

The source of the problem is a new way of processing error during buffer
reenqueueing.
Formerly (v4l2src_call.c, rev 1.50), v4l2src element sent error message and it
was 
possible to catch this message and restart pipeline. Now this situation just
skipped and as a result we lost buffers.
