Description
Traditionally the default LOV and LMV of a directory is set via MDS_SETATTR request, but user may issue MDS_SETXATTR request with XATTR_NAME_DEFAULT_LMV to set default LMV, and this code path lack check of the default from client side, and may cause crash. The latter code path should not be allowed (like what has been done for default LOV).
