Input: i8042 - remove unneeded call to i8042_interrupt()

Remove call to i8042_interrupt() from i8042_aux_write(). According
to Vojtech it may cause problems with older controllers if it is
called right after real interrupt. Also it is not needed anymore
since we register IRQs early and not waiting for serio ports to
be opened.
