[PATCH] venus: vdec: fix decoded data size

[Vikash Garodia <vgarodia@codeaurora.org>]

Exisiting code returns the max of the decoded size and buffer size.
It turns out that buffer size is always greater due to hardware
alignment requirement. As a result, payload size given to client
is incorrect. This change ensures that the bytesused is assigned
to actual payload size, when available.
