[ Upstream commit a4b7064d34186cf4970fe0333c3b27346cf8f819 ]
If i2c_smbus_write_byte_data() fails in al3010_init(), al3010_set_pwr(false) is not called.
In order to avoid such a situation, move the devm_add_action_or_reset() witch calls al3010_set_pwr(false) right after a successful al3010_set_pwr(true).
