i810fb: fix console switch regression
Since4c7ffe0b9f
("fbdev: prevent drivers that have hardware cursors from calling software cursor code") every call of i810fb_cursor fails with -ENXIO because of a incorrect "!". This hasn't struck untileaa0ff15c3
("fix ! versus & precedence in various places") surrounded the expression with braces, so that the intended behavior was inverted. That caused 'pixel waste' - the same line of multi-colored pixels repeated over the whole screen - during console switch. This switches back to the original pre-4c7ffe0 behavior.
