In case an ISCSI Transport ID has no ISID, port_nexus_ptr was not used to write NULL, so value from previous call might persist. I don't know, if that ever could happen, but with the change the code is cleaner, I think.

Reason is the too high loop limit (< 24) in fc_get_pr_transport_id(). The string representation of FC WWPN is 23 chars long only ("11:22:33:44:55:66:77:88"). So when i is 23, the loop body is executed a last time for the ending '\0' of the string and thus hex2bin() reports an error.
