apparmor: fix lsm_get_self_attr()
In apparmor_getselfattr() when an invalid AppArmor attribute is
requested, or a value hasn't been explicitly set for the requested
attribute, the label passed to aa_put_label() is not properly
initialized which can cause problems when the pointer value is non-NULL
and AppArmor attempts to drop a reference on the bogus label object.
