zink: fix PIPE_RESOURCE_PARAM_NPLANES with format modifier

Some format modifiers change the number of planes used by an image.
For instance AMD DCC modifiers uses 2 or 3 planes. However the
format modifier was ignored in the PIPE_RESOURCE_PARAM_NPLANES
get_param hook.

Fix this by using get_dmabuf_modifier_planes() instead of
util_format_get_num_planes().

This fixes wlroots-based compositors under zink.
