watch_queue: Drop references to /dev/watch_queue

Browse Source 
[ Upstream commit 8fe62e0c0e2efa5437f3ee81b65d69e70a45ecd2 ]

The merged API doesn't use a watch_queue device, but instead relies on
pipes, so let the documentation reflect that.

This option provides support for getting change notifications on keys
and keyrings on which the caller has View permission. This makes use
of the /dev/watch_queue misc device to handle the notification
buffer and provides KEYCTL_WATCH_KEY to enable/disable watches.
