drm/amdkfd: Fix race between scheduler and context restore
The scheduler may raise SQ_WAVE_STATUS.SPI_PRIO via SQ_CMD before
context restore has completed. Restoring SPI_PRIO=0 after this point
may cause context save to fail as the lower priority wavefronts
are not selected for execution among spin-waiting wavefronts.
Leave SPI_PRIO at its SPI-initialized or scheduler-raised value.
v2: Also fix race with exception handler
