Subject: scsi: qla2xxx: Set remove flag for all VP
Patch-mainline: v5.5-rc1
Git-commit: 6997db98d00a659d05cda23bd33c34aff546635b
References: jsc#SLE-9714 jsc#SLE-10327 jsc#SLE-10334
During driver unload, the remove flag will be set for all
scsi_qla_host/NPIV. This allows each NPIV to see the flag instead of
reaching for base_vha to search for it.
