New Revision: 163171

URL: http://svn.digium.com/view/asterisk?view=rev&rev=163171
Log:
Fix the "failed" extension for outgoing calls.  

The conversion to use ast_check_hangup() everywhere instead of checking the softhangup
flag directly introduced this problem.  The issue is that ast_check_hangup() checked
for tech_pvt to be NULL.  Unfortunately, this will be NULL is some valid circumstances,
such as with a dummy channel.

The fix is simple.  Don't check tech_pvt.  It's pointless, because the code path that
sets this to NULL is when the channel hangup callback gets called.  This happens inside
of ast_hangup(), which is the same function responsible for freeing the channel.  Any
code calling ast_check_hangup() better not be calling it after that point, and if so,
we have a bigger problem at hand.
