Commit 374146ca ("drm/vc4: Switch to drmm_mutex_init") converted, among other functions, vc4_create_object() to use drmm_mutex_init(). However, that function is used to allocate a BO, and therefore the mutex needs to be freed much sooner than when the DRM device is removed from the system. For each buffer allocation we thus end up allocating a small structure as part of the DRM-managed mechanism that is never freed, eventually leading us to no longer having any free memory anymore. Let's switch back to mutex_init/mutex_destroy to deal with it properly.
