 Description   

In mdt_reint_setattr, it should only lock sub_stripes
for certain attributes, for other attributes, it only
needs to set on the master object.

In lod_object_unlock, since it already know the lock
handle, it can release the lock directly, instead of
load and holding the sub-stripe object.
