target: Allow AllRegistrants to re-RESERVE existing reservation
This patch changes core_scsi3_pro_release() logic to allow an
existing AllRegistrants type reservation to be re-reserved by
any registered I_T nexus.
This addresses a issue where AllRegistrants type RESERVE was
receiving RESERVATION_CONFLICT status if dev_pr_res_holder did
not match the same I_T nexus, instead of just returning GOOD
status following spc4r34 Section 5.9.9:
"If the device server receives a PERSISTENT RESERVE OUT command
with RESERVE service action where the TYPE field and the SCOPE
field contain the same values as the existing type and scope
from a persistent reservation holder, it shall not make any
change to the existing persistent reservation and shall complete
the command with GOOD status."
