iio: magnetometer: ak8975: Fix the error handling in ak8975_power_on()
commit 3a26787dacf04257a68b16315c984eb2c340bc5e upstream.
When the driver fails to enable the regulator 'vid', we will get the
following splat:
[ 79.955610] WARNING: CPU: 5 PID: 441 at drivers/regulator/core.c:2257 _regulator_put+0x3ec/0x4e0
[ 79.959641] RIP: 0010:_regulator_put+0x3ec/0x4e0
[ 79.967570] Call Trace:
[ 79.967773] <TASK>

[ 79.968608] i2c_device_probe+0x766/0x940
Fix this by disabling the 'vdd' regulator when failing to enable 'vid'
regulator.
