Subject: [PATCH] mpathpersist: Fix Register and Ignore with 0x00 SARK
When the Register and Ignore command is run with sg_persist, if a 0x00
Service Action Reservation Key is given or the --param-sark option is
not used at all, sg_persist will clear the registration. mpathpersist
will fail with an error. This patch fixes mpathpersist to work like
sg_persist in this case.
