torture: Exclude "NOHZ tick-stop error" from fatal errors

Browse Source 
commit 8d68e68a781db80606c8e8f3e4383be6974878fd upstream.

The "NOHZ tick-stop error: Non-RCU local softirq work is pending"
warning happens frequently and appears to be irrelevant to the various
torture tests.  This commit therefore filters it out.

If there proves to be a need to pay attention to it a later commit will
add an "advice" category to allow the user to immediately see that
although something happened, it was not an indictment of the system
being tortured.
