power: supply: axp288_charger: Fix unchecked return value

Browse source

Currently there is no check on platform_get_irq() return value
in case it fails, hence never actually reporting any errors and
causing unexpected behavior when using such value as argument
for function regmap_irq_get_virq().

Fix this by adding a proper check, a message reporting any errors
and returning *pirq*
