Harshit Mogalapalli 10f49cdfd5 i915/perf: Fix NULL deref bugs with drm_dbg() calls 
commit 471aa951bf upstream.

When i915 perf interface is not available dereferencing it will lead to
NULL dereferences.

As returning -ENOTSUPP is pretty clear return when perf interface is not
available.

Fixes: 2fec539112 ("i915/perf: Replace DRM_DEBUG with driver specific drm_dbg call")
