 * Name: binfmt_exit
 *
 * Description:
 *   This function may be called when a tasked loaded into RAM exits.
 *   This function will unload the module when the task exits and reclaim
 *   all resources used by the module.
 *
 * Input Parameters:
 *   bin - This structure must have been allocated with kmm_malloc() and must
 *         persist until the task unloads
 *
 * Returned Value:
 *   This is a NuttX internal function so it follows the convention that
 *   0 (OK) is returned on success and a negated errno is returned on
 *   failure.
 *
