ast_device_state() gets called in two different ways. The first way is when
called from elsewhere in Asterisk to find the current state of a device. In that case, we want to use the cached value if it exists. The other way is when processing a device state change. In that case, we do not want to check the cache because returning the last known state is counter productive. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@133945 65c4cc65-6c06-0410-ace0-fbb531ad65f3
