gpio: drop retval check enforcing from gpiochip_remove()

commit 14c8a620ba436511b1347c592633befa49535176 upstream.

As we start to decomission the return value from gpiochip_remove()
the compilers emit warnings due to the function being tagged
__must_check. So drop this until we remove the return value
altogether.
