vcs: prevent write access to vcsu devices
commit 0c9acb1af77a3cb8707e43f45b72c95266903cee upstream.
Commit d21b0be246bf ("vt: introduce unicode mode for /dev/vcs") guarded
against using devices containing attributes as this is not yet
implemented. It however failed to guard against writes to any devices
as this is also unimplemented.
