Subject: [PATCH AUTOSEL 5.15 3/4] nvmet: use NVME_CMD_EFFECTS_CSUPP instead of open coding it

From: Christoph Hellwig <hch@....de>

[ Upstream commit 61f37154c599cf9f2f84dcbd9be842f8645a7099 ]

Use NVME_CMD_EFFECTS_CSUPP instead of open coding it and assign a
single value to multiple array entries instead of repeated assignments.
