Input: i8042 - retry failed CTR writes when resuming

There are systems that fail in i8042_resume() with

i8042: Can't write CTR to resume

as i8042_command(&i8042_ctr, I8042_CMD_CTL_WCTR) fails even though the
controller claimed itself to be ready before.

One retry after failing write fixes the problems on the failing systems.
