power: supply: act8945a_charger: fix of_irq_get() error check
of_irq_get() may return any negative error number as well as 0 on failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to devm_request_irq() -- that function expects *unsigned int*,
so would probably fail anyway when a large IRQ number resulting from a
conversion of a negative error number is passed to it... This, however,
is incorrect behavior -- error number is not IRQ number.
Check for 'irq <= 0' instead and return -ENXIO from probe if of_irq_get()
returned 0.
