Creation of the response to READ FULL STATUS fails for FC
based reservations. 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.
