When a lock is first locked, this checks to see if the last lock in the list was one that was failed to be locked. If it is, then that was a lock that we're no longer sitting in a trylock loop trying to lock, so just remove it. (inspired by issue #11712) ........ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@104103 65c4cc65-6c06-0410-ace0-fbb531ad65f3
