[Intel-gfx] [PATCH] drm/i915/fbc: drop uncore locking around i8xx/i965 fbc nuke

[Jani Nikula <jani.nikula@intel.com>]

The locking should not be needed after commits de5bd083d247
("drm/i915/fbc: Skip nuke when flip is pending") and 7cfd1a18c5f9
("drm/i915: Remove remaining locks from i9xx plane udpates").
