i810fb: fix console switch regression
Since 4c7ffe0b9f7f40bd818fe3af51342f64c483908e ("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 until eaa0ff15c30dc9799eb4d12660edb73aeb6d32c5 ("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.
