Subject[patch 17/26] Fix module refcount leak in __set_personality()
From: Sergey Vlasov <vsu@altlinux.ru>

If the change of personality does not lead to change of exec domain,
__set_personality() returned without releasing the module reference
acquired by lookup_exec_domain().

This patch was already included in Linus' tree.
