[SCSI] scsi_dh_alua: Re-enable STPG for unavailable ports
A quote from SPC-4: "While in the unavailable primary target port asymmetric access state, the device server shall support those of the following commands that it supports while in the active/optimized state: [ ... ] d) SET TARGET PORT GROUPS; [ ... ]". Hence re-enable sending STPG to a target port group that is in the unavailable state.
