gpio: sim: initialize a managed pointer when declaring it
[ Upstream commit 9f93f18305f5777820491e6ab9b34422c160371b ]
Variables managed with __free() should typically be initialized where
they are declared so that the __free() callback is paired with its
counterpart resource allocator. Fix the second instance of using
__free() in gpio-sim to follow this pattern.
