drm/i915: struct_mutex is not required for allocating the framebuffer
We do not need the BKL struct_mutex in order to allocate a GEM object, nor to create the framebuffer, so resist the temptation to take the BKL willy nilly. As this changes the locking contract around internal API calls, the patch is a little larger than a plain removal of a pair of mutex_lock/unlock.
