nvme: don't return an error from nvme_configure_metadata

[ 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.
