Summary: dialog: crash while handling BYE for redirected calls

Initial Comment:
If 3xx replies are handled by uac module and the call is profiled, the folowing crash occurs when the call is terminated:

Program terminated with signal 11, Segmentation fault.
#0  0x40227a9f in destroy_linkers (linker=0x0) at dlg_profile.c:230
230					p_entry->first->prev = p_entry->first->prev->prev;

(gdb) print p_entry
$1 = (struct dlg_profile_entry *) 0x40424f2c
(gdb) print p_entry->first
$2 = (struct dlg_profile_hash *) 0x0


As a side effect, the profiling count is incremented twice when the redirection occurs, despite the fact that the profiling is set only for the first call (there is not profiling set for the redirected call).
