tpm: fix RC value check in tpm2_seal_trusted
commit 7d761119a914ec0ac05ec2a5378d1f86e680967d upstream.
The error code handling is broken as any error code that has the same
bits set as TPM_RC_HASH passes. Implemented tpm2_rc_value() helper to
parse the error value from FMT0 and FMT1 error codes so that these types
of mistakes are prevented in the future.
Fixes: 5ca4c20cfd37 ("keys, trusted: select hash algorithm for TPM2 chips")
