[PATCH] venus: vdec: fix decoded data size

From: Vikash Garodia
Date: Mon Jul 02 2018 - 03:44:25 EST

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.
