bq2515x_get_charge_disable() returns bool even though reading the
charger-disable state can fail. A negative error is therefore converted to
true, so POWER_SUPPLY_PROP_STATUS reports NOT_CHARGING with success instead
of propagating the failure. The GPIO read is not checked for errors either.

Return an int from the helper, check both reads, and only convert a valid
charger-disable state to the charging-status boolean.
