Subject: [PATCH] proto: remove vestiges of ei_device.capability

This is now obsolete after [1]. The ei_device.interface event announces
which interfaces are available on the device so we don't need
documentation to say "it's a bug to send this request if the device
doesn't have the capability" since the client won't have the interface
to begin with.

Fixes: a902d5dbd859 ("protocol: replace the capabilities enum with an interface list")
