iio: temperature: max31856: fix uninitialized error return

Currently if mask is neither CHAN_INFO_RAW or CHAN_INFO_SCALE then
then an uninitialized error return 'ret' is returned. Fix this by
adding a default case that ensures -EINVAL is returned for this
specific case.

Addresses-Coverity: ("Uninitialized scalar variable")
