New Revision: 272052

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=272052
Log:
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.
