iio: magnetometer: yas530: Fix memchr_inv() misuse

The call to check if the calibration is all zeroes is doing
it wrong: memchr_inv() returns NULL if the the calibration
contains all zeroes, but the check is for != NULL.

Fix it up. It's probably not an urgent fix because the inner
check for BIT(7) in data[13] will save us. But fix it.
