Revert commit r22596.
commit ab8610aa176c13b5e25a2d8770df28a14665e169
Author: koorogi <koorogi@9553f0bf-9b14-0410-a0b8-cfaf0461ba5b>

The vflip filter does not need to keep ownership of a picture reference.
Avoid creating and releasing useless extra picture references in the
start_frame and end_frame callbacks.
Originally committed as revision 22596 to svn://svn.ffmpeg.org/ffmpeg/trunk
The new reference creation is required when the linesizes are used by the
previous filters in the filterchain, for example as in "pad=W:H:X:Y,vflip".
