Hi,

Attached is a small patch to avoid throwing an exception when the
Forwarded-For HTTP header contains something that doesn't parse as an
IP address.

/usr/share/lua/5.2/prosody/util/ip.lua:233: attempt to index local
'ipA' (a nil value)
stack traceback:
/usr/share/lua/5.2/prosody/util/ip.lua:233: in function 'match_ip'
