Subject: [PATCH 2/5] tuna: Handle get_policy_and_rtprio exceptions

In tuna-cmd.py, if a thread list is passed along with the
'--priority' flag, tuna.get_policy_and_rtprio() is called twice, first
directly, and then again by tuna.threads_set_priority(). The
expectation is that tuna.threads_set_priority will handle exceptions
raised by tuna.get_policy_and_rtprio(). This results in a failure to
handle exceptions that are raised by the initial direct call to
tuna.get_policy_and_rtprio().

Handle exceptions that may be raised during direct calls to
get_policy_and_rtprio in tuna-cmd.py.
