[host] nvfbc: update cursor position on shape change

Browse Source 
This is because we keep track of the top-left corner of the cursor, not
the location of the hotspot. When the cursor shape changes, the hotspot
location may also change. When it does, the position of the top-left
corner changes and requires an update.

In the case that we do not have the current cursor position, which
happens on startup, we do not generate this update.
