da9052-battery: Don't free IRQ that wasn't requested
We should decrement "i" before doing the free_irq(). If we call this
because request_threaded_irq() failed then we don't want to free the
thing which failed. Or in the case where we get here because
power_supply_register() failed then the original codes does a read past
the end of the array.
