[PATCH] render: don't bother with animated cursors on floating slaves (#39989)

[Peter Hutterer]

In the case of floating slave devices that is reattached to a master with an
animated cursor, that cursor may "jump outside" it's window confines. Since
floating slaves never display a cursor anyway, we might as well short-cut
this and exit early.
