I am fighting deadlocks in chan_iax2.  I have tracked them down to a single
core issue.  You can not call find_callno() while holding a pvt lock as this
function has to lock another (every) other pvt lock.  Doing so can lead to a
classic deadlock.  So, I am tracking down all of the code paths where this
can happen and fixing them.

The fix I committed earlier today was along the same theme.  This patch fixes
some code down the path of authenticate_reply.
