[libgpiod][PATCH 02/16] tests: avoid shadowing local variables with common names in macros

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The name 'ret' if very common for local variables so change it to _ret
in test helper macros to avoid potential shadowing.
