Currently if modesetting ever fails to set a hardware cursor it will switch
to using a software cursor and never go back. Change this to try a hardware
cursor first every time a new one is set. This is needed because hardware
may be able to handle some cursors in harware and others not, or virtual
hardware may be able to handle hardware cursors at some times and not
others.

Re-sending as this did not seem to get noticed much the first time.
