Fix incorrect Status::NoSpace() status check (#8504) 

Summary:
If we want to check whether a Status s is NoSpace() or not, we should check the subcode instread of using s==Status::NoSpace(). Fix some of the incorrect check in the ErrorHandler.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8504

Test Plan: make check
