gpio: fix memory and reference leaks in gpiochip_add error path
commit 5539b3c938d64a60cb1fc442ac3ce9263d52de0c upstream.
Memory allocated and references taken by of_gpiochip_add and
acpi_gpiochip_add were never released on errors in gpiochip_add (e.g.
failure to find free gpio range).
Fixes: 391c970c0dd1 ("of/gpio: add default of_xlate function if device
has a node pointer")
Fixes: 664e3e5ac64c ("gpio / ACPI: register to ACPI events
automatically")

[bwh: Backported to 3.2:
- Move call to of_gpiochip_add() into conditional section rather
than rearranging gotos and labels which are in different places
here
- There's no ACPI support]
