[PATCH 5.15 552/779] nvme: dont return an error from nvme_configure_metadata

[Greg Kroah-Hartman]

From: Christoph Hellwig <hch@xxxxxx>

[ Upstream commit 363f6368603743072e5f318c668c632bccb097a3 ]

When a fabrics controller claims to support an invalidate metadata
configuration we already warn and disable metadata support.  No need to
also return an error during revalidation.
