[PATCH 1/2] power: supply: ab8500_charger: Fix an error handling path

[Christophe JAILLET]

'ret' is know to be 0 at this point, because it has not been updated by the
the previous call to 'abx500_mask_and_set_register_interruptible()'.

Fix it by updating 'ret' before checking if an error occurred.
