sys/v4l/v4lsrc_calls.c: Don't actually error out if we get another return value than

Browse Source 
Original commit message from CVS:
* sys/v4l/v4lsrc_calls.c: (gst_v4lsrc_try_capture):
Don't actually error out if we get another return value than
-EINVAL. Opposite to what I first thought, drivers have random
return values for this, although -EINVAL is the expected return
value. Since this is not fatal, we shouldn't use
GST_ELEMENT_ERROR() but just GST_ERROR_OBJECT().
