Summary:                    [patch] sig_pri_new_ast_channel should return NULL
when new_ast_channel fails to create a channel
Description: 
It appears that a non-existent channel's transfercapability was trying to
be set. This was during a kill -9 on a runaway box deadlocking in the TCP
TLS layer (which took over a minute to die, a separate matter.) But it
still looks like a bug. Patch attached.
