Subject: scsi: lpfc: move placement of target destroy on driver detach
Patch-mainline: v4.17-rc1
Git-commit: 281d61902ffbab47901f8616a38a45144627dd9e
References: bsc#1080657

Ensure nvme localports/targetports are torn down before dismantling the
adapter sli interface on driver detachment.  This aids leaving
interfaces live while nvme may be making callbacks to abort it.
