Chris Wilson 3fdc13c7a3 drm/i915: Remove (struct_mutex) locking for busy-ioctl
By applying the same logic as for wait-ioctl, we can query whether a
request has completed without holding struct_mutex. The biggest impact
system-wide is removing the flush_active and the contention that causes.

Testcase: igt/gem_busy
