ffmpeg | branch: master | Sebastien Zwickert <dilaroga at gmail.com> | Sat Jun 20 13:19:29 2015 +0200| [c06fdacc3dc706e70d953917fea845532d3703ca] | committer: Clément Bœsch

vda: unlock the pixel buffer base address.

The pixel buffer base address is never unlocked this causes
a bug with some pixel format types that are produced natively
by the hardware decoder: the first buffer was always used.
Unlock the pixel buffer base address fixes the issue.
