Most error branches following the call to pmcraid_get_free_cmd contain a call to pmcraid_return_cmd. This patch add these calls where they are missing.
Moreover, most error branches following the call to class_create contain a call to class_destroy. This patch add these calls where they are missing.
This issue was found with Hector.
