BUG#22530768 Innodb freeze running REPLACE statements

we can see from the hang stacktrace, srv_monitor_thread is blocked
when getting log_sys::mutex, so that sync_arr_wake_threads_if_sema_free
cannot get a change to break the mutex deadlock.

The fix is simply removing any mutex wait in srv_monitor_thread.

Patch is reviewed by Sunny over IM.
