As warned by Coverity:
CID 1415211 (#1 of 1): Unused value (UNUSED_VALUE)assigned_value:
Assigning value -22 to ret here, but that stored value is
overwritten before it can be used.

On all cases where the there's a goto 'unlock_out' or 'streamof',
ret was filled with a non-sero value. It toesn't make sense to override
such error code with a videobuf_streamoff() error.
