iio: magnetometer: ak8974: Silence deferred-probe error

Browse Source 
It's not uncommon that voltage regulator becomes available later during
kernel's boot process. This patch adds info message about unavailable
regulators in a case of the deferred-probe error and also amends the
error message with a error code.
