[PATCH 5/5] nvme: re-read ANA log page after ns scan completes

[Hannes Reinecke <hare@kernel.org>]

From: Hannes Reinecke <hare@suse.de>

When scanning for new namespaces we might have missed an ANA AEN,
so we should always re-read the ANA log page after scanning to ensure
we don't miss updates there.
