The surface can have an undefined resource in certain situations (such
as with xwayland). So, since NULL is a valid state for this parameter,
and since the wl_resource_*, etc. calls require their parameters to be
non-NULL, make a practice of always checking the surface resource before
making wayland calls.
update v2:
* Fix some c/p errors for pointer names
* Drop null ptr check in add_popup_grab; probably redundant now
