Subject: [PATCH net 0/4] net-sysfs: check device is present when showing paths

A sysfs reader can race with a device reset or removal.

This was fixed for speed_show with commit 4224cfd7fb65 ("net-sysfs: add
check for netdevice being present to speed_show") so add the same check
to carrier, duplex, testing, and dormant paths.

Submitting as separate patches to make Fixes reporting accurate.
