I tested:

PASS: make THREADS=2 THREAD_TYPE=frame fate-vp8
PASS: make THREADS=1 THREAD_TYPE=frame fate-vp8
PASS: make THREADS=8 THREAD_TYPE=frame fate-vp8
PASS: make THREADS=6 THREAD_TYPE=frame fate-vp8

FAIL: make THREADS=2 THREAD_TYPE=tile fate-vp8
FAIL: make THREADS=1 THREAD_TYPE=tile fate-vp8
FAIL: make THREADS=8 THREAD_TYPE=tile fate-vp8
FAIL: make THREADS=6 THREAD_TYPE=tile fate-vp8

The vp8-2451 case fails, above, for tile thread type *without* this patch, too.

This patch also fixes the issues reported at:

https://github.com/intel/media-driver/issues/1028 and
