tests/gem_userptr_blits: Race between object creation and multi-threaded mm ops
Userptr v23 was not thread safe against memory map operations and object
creation from separate threads. MMU notifier callback would get triggered
on a partially constructed object causing a NULL pointer dereference.
This test excercises that path a bit. In my testing it would trigger it
every time and easily, but unfortunately a test pass here does not guarantee
the absence of the race.
v2: Added explicit cancellation point and removed the stop flag.
Use only igt_assert().
