From: John Harrison <John.C.Harrison at Intel.com>

Fix for a deadlock issue between the GuC busyness stats worker and GT
resets. Also fix kernel contexts not getting the correct scheduling
priority at start of day.

v2: Rename existing uses of _trylock rather than adding a _noretry
version. Also improve the comment a bit.
