tests/gem_reset_stats : mask off ring_stop bits
Function check_gpu_ok checks to make sure that any hangs
have cleared by testing for (flags == 0). Some tests set
the STOP_RINGS_ALLOW_BAN and STOP_RINGS_ALLOW_ERRORS flags
but these do not get cleared by an individual ring reset,
(a feature added recently to the driver), leading the
check_gpu_ok function to think that the gpu is still hung.
So I mask the flags with STOP_RING_ALL, to ignore the mode
bits and look only at the bits that stop the rings.
Once gpu_check_ok sees that the gpu is not hung I write 0
to stop_rings in order to clear it completely. This is
because igt_set_stop_rings will only write to stop_rings
if either a) they are currently 0 or b) we are writing 0.
If we leave the mode bits set then subsequent calls to
igt_set_stop_rings to create hangs will fail.
