[SPARK-19722] [SQL] [MINOR] Clean up the usage of EliminateSubqueryAliases
### What changes were proposed in this pull request?
In the PR https://github.com/apache/spark/pull/11403, we introduced the
function `canonicalized` for eliminating useless subqueries. We can simply
replace the call of rule `EliminateSubqueryAliases` by the function
`canonicalized`.
After we changed the view resolution and management, the current reason why
we keep `EliminateSubqueryAliases ` in optimizer becomes out-of-dated. Thus,
this PR also update the reason to `eager analysis of Dataset`.
