power: supply: z2_battery: Fix possible memleak in z2_batt_probe()

[ Upstream commit 955bee204f3dd307642c101b75e370662987e735 ]

If devm_gpiod_get_optional() returns error, the charger should be
freed before z2_batt_probe returns according to the context. We
fix it by just gotoing to 'err' branch.
