Don't crash on torrc Vi[rtualAddrNetworkIPv[4|6]] with no option value

Browse Source 
Check for a missing option value in parse_virtual_addr_network
before asserting on the NULL in tor_addr_parse_mask_ports.
This avoids crashing on torrc lines like Vi[rtualAddrNetworkIPv[4|6]]
when no value follows the option.

Bugfix on 0.2.3 (de4cc126cb on 24 November 2012), fixes #14142.
