drm/i915: Check for dev->primary->master before dereference.
upstream commit: 98787c057fdefdce6230ff46f2c1105835005a4c
I've hit the occasional oops inside i915_wait_ring() with an indication of
a NULL derefence of dev->primary->master. Adding a NULL check is
consistent with the other potential users of dev->primary->master.
