Failing Debug Assert in TdsParserStateObject.ReadAsyncCallback

[corivera]

Fails in SqlClient manual tests when running with Managed SNI in debug mode.

The repro scenario in the following issue hits this debug assert immediately, so it may be related.

This is a less detailed report of the behaviour in https://github.com/dotnet/corefx/issues/33930 . Can the other issue be re-opened and moved to SqlClient then this one closed as a dupe of it @divega ?
The other could/should also be assigned to @saurabh500 as he and i have discussed it at some length when i've tried to fix it and it needs his domain model perspective to fix properly.

Ok @Wraith2 I will reactivate the other issue and move both to the SqlClient repo.

Note for the SqlClient team: this can probably be closed as duplicate of https://github.com/dotnet/corefx/issues/33930 (now #108).
