sthal: fix deadlock issue during ssr
When ssr is happened at the beginning of detection, session lock
will be held by snd_monitor callback thread when processing the
ssr event, it finally will wait for detection callback thead to
exit to finish ssr event processing.
While at the same time, detection callback thread also need to
hold the session lock which is already held by snd_monitor callback
thread, thus causing deadlock issue.
Check if ssr in progress in detection callback thread before
acquring session lock.
