Subject: iio: adc: max11410: fix incomplete vref buffer mask
VREFP bit was missing from channel configuration mask and VREFN bit was
included twice instead which fails to enable positive reference buffer when
requested by a channel. Channels that don't enable vrefp buffer were not
affected.
Fixes: a44ef7c46097 ("iio: adc: add max11410 adc driver")
