[Libva] [PATCH 2/3] jpeg_enc: Fix the quatisation matrix scaling.

[sreerenj.balachandran at intel.com]

From: Sreerenj Balachandran <sreerenj.balachandran at intel.com>

The misplaced parentheses are causing wrong value assignment
to the quatization matrix.

This will allow the ecoding when quality > 50.
Otherwise it will simply generate garbage in encoded video
for any quality factor greater than 50
