[Intel-gfx] [PATCH] drm/i915/selftests: Move test flush to outside vm->mutex

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

As per our locking rules it is not allowed to wait on requests while
holding locks. In this case we were trying to idle the GPU while holding
the vm->mutex.
