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. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
