Andrew Turner bb8c68b253 acpi_gpiobus: Fix cleanup on set flags failure 
When GPIOBUS_PIN_SETFLAGS fails we called gpiobus_free_ivars to clean
up the contents of the ivar, then would free the ivar. This lead to a
use-after-free as the ivar had already been set on the child so
gpiobus_child_deleted would try to free it again.

Fix this by removing the early cleanup and letting
gpiobus_child_deleted handle it.

Fixes:	c9e880c0ce ("gpiobus: Use a bus_child_deleted method to free ivars for children")
