Summary:                    [patch] chan_sip does not decrease module refcount
on deferred BYE
Description: 
When sip_hangup clears a channel with SIP_DEFER_BYE_ON_TRANSFER set, it
will return without calling ast_module_unref().  This causes the use
counter for chan_sip to increase over time, making it impossible to unload
the module without restarting Asterisk.

The attached patch calls ast_module_unref() immediately before returning
in the deferred BYE case.  I believe this is safe, because the SIP dialog
involved will still be freed when the containing AO2 object's refcount hits
0 as part of module_unload.
