msm: kgsl: Increase priority of RT thread

Browse source 
We need kgsl_worker_thread to preempt
all userspace surfaceflinger threads to
avoid a possible deadlock.

This will prevent the SF
threads from "stealing" cputime from
kgsl_worker_thread.
This is important, since kgsl_worker_thread
executes work which blocks SF from proceeding.
