Jarkko Sakkinen df745e2509 tpm: Lazily flush the auth session 
Move the allocation of chip->auth to tpm2_start_auth_session() so that this
field can be used as flag to tell whether auth session is active or not.

Instead of flushing and reloading the auth session for every transaction
separately, keep the session open unless /dev/tpm0 is used.
