Summary: [patch] Asterisk is core dumping with LibPRI
Description:
We have a system using asterisk 1.4.32 and libpri libpri-1.4.11.4. I have
attached a backtrace that shows it is failing with libpri. The logs always
show the following line right before asterisk crahes.

Segfault in pri_schedule_del() - ctrl value is invalid.
Validate the given call pointer in libpri API calls. If the call pointer
is not an active call record then a complaint message is issued and the
API call aborts. The call pointer is likely stale.
This patch is defensive. More information is needed to figure out why
Asterisk still has a call pointer during its hangup sequence.
