wayland: Always send wl_pointer.axis after .axis_value120/discrete

Browse Source 
The wl_pointer.axis_discrete axis (applicable to wl_seat <= v8) is
meant to be sent together with wl_pointer.axis events in the same
frame. And the wl_pointer.axis_value120 event replaces it in
wl_seat >= v9, but has the same relation with the other information
available in a frame.

This emission should not be conditional to anything, so drop the
various checks leading to maybe sending wl_pointer.axis or not.

This fixes emission of wl_pointer.axis in conjunction with discrete
events, for some combinations of versions and (non)value120 mice.
