drm/i915: Update ifdeffery for mutex->owner

In commit 7608a43d ("locking/mutexes: Use MUTEX_SPIN_ON_OWNER when
appropriate") the owner field in the mutex was updated from being
dependent upon CONFIG_SMP to using optimistic spin. Update our peek
function to suite.

Fixes:7608a43d ("locking/mutexes: Use MUTEX_SPIN_ON_OWNER...")
