staging:iio:naming in the EV_BIT macro fix.

Should always have been IIO_EV_DIR_MAX as that's what it actually controls. Also reduced the number to 4 as not yet seen a case needing more and this is not userspace visible anyway. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
