On SIG Down we must not fail a call instead try hunting for another.
The only time we can fail the call and not bother hunting is
if sng_cc_resource_check fails.
Took out configuration retry as the config code is now
fixed in sng_ss7 library. Transaction id fix.
Unit Tested:
NSG UP -- start full load
kill NSG
NSG UP again on full load
make sure it comes up fine.
