clients: keyboard: Prevent NULL context in 'keyboard_handle_key'

Browse source 
It can happen that the input context is exited between a key press event
and a key release event, as a result it is set to NULL. If the
'keyboard_handle_key' function is called in this case, this leads to a
crash. To prevent this, the context is checked beforehand.
