  [mlir][bufferization] Fix SimplifyClones with dealloc before cloneOp (#79098)

The SimplifyClones pass relies on the assumption that the deallocOp
follows the cloneOp. However, a crash occurs when there is a
redundantDealloc preceding the cloneOp. This PR addresses the issue by
ensuring the presence of deallocOp after cloneOp. The verification is
performed by checking if the loop of the sub sequent node of cloneOp
reaches the tail of the list.

Fix #74306
