Fix parsing of optional portnr in iscsi target IP (#525118)

This patch fixes 2 issues with the parsing of the optional portnr in
iscsi target IP's:
1) We don't want to include the : in the portno, so port = target[idx:]
   should be port = target[idx+1:]
2) An IPV6 IP always includes the : character, so specifying the port
   was mandatory with IPV6, this patch looks for "]:" inside the
   string to determine if a port is present for IPV6 strings.
