Zheyu Ma ca2b54b6ad iio: magnetometer: ak8975: Fix the error handling in ak8975_power_on() 
commit 3a26787dac 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.
