Use the correct channel2 member instead of channel when dealing with sysfs
reads/writes

as a bonus, m is renamed to mask
Which would have been relevant back when it was a mask.  Still it doesn't
make things worse, so never mind ;)  One day someone might be bored enough
to clean up all the places in read_raw etc where the variable is called mask
but is infact a straight number.

Applied to the fixes-togreg branch of iio.git  - initially pushed out as testing
for the autobuilders to thoroughly hammer.
