gpio: gpiolib: remove shadowed variable

After refactoring, we had two variables for the same thing. Remove the
second declaration, one is enough here. Found by cppcheck.

drivers/gpio/gpiolib.c:2551:17: warning: Local variable 'ret' shadows outer variable [shadowVariable]

Fixes: d377f56f34f5 ("gpio: gpiolib: Normalize return code variable name")
