[PATCH 5.10 146/599] nvme: cleanup __nvme_check_ids

[Greg Kroah-Hartman]

From: Christoph Hellwig <hch@xxxxxx>

[ Upstream commit fd8099e7918cd2df39ef306dd1d1af7178a15b81 ]

Pass the actual nvme_ns_ids used for the comparison instead of the
ns_head that isn't needed and use a more descriptive function name.
