Subject: Don't try to lock/unlock an uninitialized lock on a dahdi_pri.
X-Git-Tag: 11.0.0-beta1~2794

Don't try to lock/unlock an uninitialized lock on a dahdi_pri.

This small changes prevents destroy_all_channels() from accessing a lock on an
unused dahdi_pri struct, resolving a ton of ERRORs that get spewed out when
shutting Asterisk down gracefully.
