block: sed-opal: Change the check condition for regular session validity

This patch changes the check condition for the validity/authentication
of the session.

1. The Host Session Number(HSN) in the response should match the HSN for
   the session.
2. The TPER Session Number(TSN) can never be less than 4096 for a regular
   session.
