scsi: target: core: Fix preempt and abort for allreg res
Match a key only if SARK is not zero according to SPC-4 and the comment
above the code:
If an all registrants persistent reservation is present and the SERVICE
ACTION RESERVATION KEY field is set to zero, then all registrations
shall be removed except for that of the I_T nexus that is being used
for the PERSISTENT RESERVE OUT command;
Without this patch in case of SARK==0 no registrants will be removed.
