drm/i915: Check for allocation failure
The memory allocation for C is not being null checked and hence we
could end up with a null pointer dereference. Fix this with a null
pointer check. (I really should have noticed this when I was fixing an
earlier issue.)

drm/i915: Check C for null pointer rather than B
There are two occasions where pointer B is being check for a NULL
when it should be pointer C instead. Fix these.

drm/i915: Import the kfence selftests for i915_sw_fence
A long time ago, I wrote some selftests for the struct kfence idea. Now
that we have infrastructure in i915/igt for running kselftests, include
some for i915_sw_fence.
