nvme-multipath: don't inherit LBA-related fields for the multipath node

Browse source

Linux 6.9 made the nvme multipath nodes not properly pick up changes when
the LBA size goes smaller after an nvme format.  This is because we now
try to inherit the queue settings for the multipath node entirely from
the individual paths.  That is the right thing to do for I/O size
limitations, which make up most of the queue limits, but it is wrong for
changes to the namespace configuration, where we do want to pick up the
new format, which will eventually show up on all paths once they are
re-queried.

Fix this by not inheriting the block size and related fields and always
for updating them.
