Carlos Garnacho d24be90941 backends/native: Fix accounting of cursor overlay inhibition
We react on changes to has_hw_cursor, but always try to inhibit if
there is no cursor sprite. While this looks like a reasonable optimization
with the typical situation of one cursor renderer, it may fall into
inhibiting twice without knowing to unwind, e.g.:

1. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> inhibit
2. has_hw_cursor: FALSE, cursor_sprite: NULL -> inhibit
3. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> uninhibit, but once

And this may also result in the CLUTTER_PAINT_FLAG_NO_CURSORS flag
staying on for Tablet cursors, that (so far) always use overlay paths.
This results in invisible tablet cursors after using the mouse at
least once.
