In appfs, find_protectable_free() must have skip_protection argument set to 0

[tyler-gilbert]

Code snippet from appfs_util_root_create()

		//find space for the code -- this doesn't need to be protectable
		code_start_addr = find_protectable_free(dev, type, dest->exec.code_size, &page, 0);
		if ( code_start_addr == (u32)-1 ){
			return SYSFS_SET_RETURN(ENOSPC);
		}

The last arg of find_protectable_free() should be 1 (because files don't need to be a in protectable region) but doing that causes problems.
