Jarkko Sakkinen ec5d9a750e tpm: Mask TPM RC in tpm2_start_auth_session()
commit 539fbab378 upstream.

tpm2_start_auth_session() does not mask TPM RC correctly from the callers:

[   28.766528] tpm tpm0: A TPM error (2307) occurred start auth session

Process TPM RCs inside tpm2_start_auth_session(), and map them to POSIX
error codes.
