fs: fix do_fsload() handling of optional arguments
Most arguments to the shell command do_fsload() implements are optional. Fix the minimum argc check to respect that. Cater for the situation where argv[2] is not provided. Enhance both do_fsload() and do_ls() to check the maximum number of arguments too. While this check would typically be implemented via U_BOOT_CMD()'s max_args parameter, if these functions are called directly, then that check won't exist. Finally, alter do_ls() to check (argc >= 4) rather than (argc == 4) so that if the function is enhanced to allow extra arguments in the future, this test won't need to be changed at that time.
