iio: imu: mpu6050: Replace devm_add_action() followed by failure action with devm_add_action_or_reset()

devm_add_action_or_reset() is introduced as a helper function which
internally calls devm_add_action(). If devm_add_action() fails
then it will execute the action mentioned and return the error code.
This reduce source code size (avoid writing the action twice)
and reduce the likelyhood of bugs.
