Revert commit 1997e6259, which causes double brackets on ipv6
inaddr_any addresses.
Since we have np_sockaddr, if we need a textual representation we can
use "%pISc".
Change iscsit_add_network_portal() and iscsit_add_np() signatures to remove
*ip_str parameter.
Fix and extend some comments earlier in the function.
Tested to work for :: and ::1 via iscsiadm, previously :: failed, see
https://bugzilla.redhat.com/show_bug.cgi?id=1249107 .
