If amdgpu_cs_query_fence_status terminates prematurely the BO
sometimes is unmapped before helper thread writes a vlaue
into it causing a segfault.

The test stalls the CP, until RCA is done the test is
disabled to not disrupt regression testing.

Adding initial tests for locks detection when SW
scheduler FIFO is full.
The test works by submitting a batch of identical commands which make the CP
stall waiting for condition to become true. The condition is later satisfied
form a helper thread. Other events that happen during this time
might create deadlock situations. One such example is GPU reset
triggered by this stall when amdgpu_lockup_timeout != 0.
v2:
Increase the delay from 2 to 100 ms.
Comment out the compute test until it's working.
Typos fix.
