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.
(cherry picked from commit c06fdacc3d)
