net: sysfs: fix locking in carrier read
My previous patch added a call to linkwatch_sync_dev(),
but that of course needs to be called under RTNL, which
I missed earlier, but now saw RCU warnings from.
Fix that by acquiring the RTNL in a similar fashion to
how other files do it here.
Fixes: facd15dfd691 ("net: core: synchronize link-watch when carrier is queried")
