drm/xe: Only try to lock external BOs in VM bind

Browse Source 
We only need to try to lock a BO if it's external as non-external BOs
share the dma-resv with the already locked VM. Trying to lock
non-external BOs caused an issue (list corruption) in an uncoming patch
which adds bulk LRU move. Since this code isn't needed, remove it.
