drm/i915/guc/slpc: Remove BUG_ON in guc_submission_disable

Browse Source 
The assumption when it was added was that GT would not be
holding any gt_pm references. However, uc_init is called
from gt_init_hw, which holds a forcewake ref. If SLPC
enable fails, we will still be holding this ref, which will
result in the BUG_ON.
