[Mesa-dev] [PATCH] nir/clone: Free clone_state after use

[Eduardo Lima Mitev]

In nir_cf_list_clone(), a state_clone object is initialized but never
freed, causing a memory leak. If the remap_table argument is NULL,
init_state will create a hash table for it, and that's what
free_clone_state is supposed to free.
