ntb_hw_switchtec: Keep track of the number of LUT windows used by the driver

This is a prep patch in order to support the crosslink feature which will
require the driver to use another reserved LUT window. To simplify this,
we add some code to track the number of reserved LUT windows in use
instead of assuming this is always 1.
