commit 6c3c9baa upstream. This patch fixes an issue with AllRegistrants reservations where an unregister operation by the I_T nexus reservation holder would incorrectly drop the reservation, instead of waiting until the last active I_T nexus is unregistered as per SPC-4. This includes updating __core_scsi3_complete_pro_release() to reset dev->dev_pr_res_holder with another pr_reg for this special case, as well as a new 'unreg' parameter to determine when the release is occuring from an implicit unregister, vs. explicit RELEASE. It also adds special handling in core_scsi3_free_pr_reg_from_nacl() to release the left-over pr_res_holder, now that pr_reg is deleted from pr_reg_list within __core_scsi3_complete_pro_release().
