[PATCH =v2 3/3] tpm: selftest: cleanup after unseal with wrong auth/policy test

[Tadeusz Struk]

Unseal with wrong auth or wrong policy test affects DA lockout
and eventually causes the tests to fail with:
"ProtocolError: TPM_RC_LOCKOUT: rc=0x00000921"
when the tests run multiple times.
Send tpm clear command after the test to reset the DA counters.
