    console: use more appropriate domain RCU-locking function
    
    While both 19afff14b4cb ("xen: support console_switching between Dom0
    and DomUs on ARM") and 1ee1e4b0d1ff ("xen/arm: Allow vpl011 to be used
    by DomU") were part of the same series (iirc), the latter correctly used
    rcu_lock_domain_by_id() in console_input_domain(), whereas the former
    for some reason used rcu_lock_domain_by_any_id() instead, despite that
    code only kind of open-coding console_input_domain(). There's no point
    here to deal with DOMID_SELF, which is the sole difference between the
    two functions.
