[mlir][Transforms][NFC] GreedyPatternRewriteDriver: Remove redundant worklist management code (#74796)

Do not add the previous users of replaced ops to the worklist during
`notifyOperationReplaced`.

The previous users are modified inplace as part of
`PatternRewriter::replaceOp`, which calls
`PatternRewriter::replaceAllUsesWith`. The latter function updates all
users with `updateRootInPlace`, which already puts all previous users of
the replaced op on the worklist. No further worklist management work is
needed in the `notifyOperationReplaced` callback.
