nvme: Elaborate on cache maintenance operation in get/set_features



At the moment the nvme_get_features() and nvme_set_features() functions
carry a (somewhat misleading) comment about missing cache maintenance.

As it turns out, nvme_get_features() has no caller at all in the tree,
and nvme_set_features' only user doesn't use a DMA buffer.

Mention that in the comment, and leave some breadcrumbs for the future,
should those functions attract more users.
