iio: health: max30102: Switch to sparse friendly iio_device_claim/release_direct()

Browse Source 
These new functions allow sparse to find failures to release
direct mode reducing chances of bugs over the claim_direct_mode()
functions that are deprecated. This particular case is about ensuring
the mode does not change rather than ensuring we are in direct mode.
A follow up may cleanup the buffer mode claim.
