avviddec: only free config when pool doesn't take ownership

Since gst_buffer_pool_set_config() takes ownership of the config structure,
it is only necessary to free the structure before using it when the true
branch of if (gst_buffer_pool_config_validate_params) hasn't run.

gst_buffer_pool_set_config() always takes ownership of the structure
regardless of success or failure. Which means the return, checked with
if (!working_pool), has no relation to the state of the structure.
