Crash when using hagi and no servers are available.

Browse Source 
When none of the servers returned by the SRV querey respond, asterisk
crashes.  The problem is that if the loop over all the SRV entries
finishes then the srv_context has already been cleaned up.

* Make ast_srv_cleanup() check to see if the context is already cleaned
up.

(closes issue #19256)
