When unlinking a dlmfs, first it will invoke dlmfs_unlink(), and then
invoke dlmfs_evict_inode(), user_dlm_destroy_lock() is invoked in both
places, the second one from dlmfs_evict_inode() will get EBUSY error
because USER_LOCK_IN_TEARDOWN is already set in lockres.  This doesn't
affect any function, just the error log is annoying.
