[FFmpeg-cvslog] Revert needless API change in 05e84c95.

[Reimar Döffinger]

ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Wed Jun 22 18:25:49 2011 +0200| [c956907eca740f609a4e19d32b43a01fbaedff75] | committer: Reimar Döffinger

Revert needless API change in 05e84c95.

When providing a custom AVIOContex for a AVFMT_NOFILE format
only print a warning instead of erroring out.
This allows the code to work with older MPlayer versions that
just always set pb out of laziness.
