do_smhload was using a ulong to store the return value from smh_load_file. That returns an int, where -1 indicates an error. As a ulong will never be negative, smh_load_file errors were not detected and so_smhload always returned zero.

Also, when errors were spotted, do_smhload was returning 1, rather than the enumeration CMD_RET_FAILURE (which is also 1).
