Russell Bryant 747cd61edf Remove some unnecessary locking from ast_hangup(). ...

This patch removes some unnecessary locking of the channels container in
ast_hangup().  The reason this came up is that this lock can very quickly block
the entire system.  If any of the channel cleanup code decides to block, it
causes a problem for the whole system.  For example, when audiohooks get
destroyed, if that blocks for a while waiting on the mixmonitor thread to exit
because it's busy blocking on some I/O, it causes a problem for many other
threads in the meantime.
