d0d19eb82e scsi: add persistent reservation out with register feature support
To establish a persistent reservation the application client shall first
register an I_T nexus with the device server. An application client registers
with a logical unit by issuing a PERSISTENT RESERVE OUT command with REGISTER
service action or REGISTER AND IGNORE EXISTING KEY service action.

Specify Initiator Ports (SPEC_I_PT) bit and All Target Ports (ALL_TG_PT) bit
are not supported for now, the registrants belong to the I_T nexus who sends
the command.

Also Activate Persist Through Power Loss (APTPL) bit will be supported in
following patches.
