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.
