tpm: fix a race condition in tpm2_unseal_trusted()
commit d4816edfe706497a8525480c1685ceb9871bc118 upstream.
Unseal and load operations should be done as an atomic operation. This
commit introduces unlocked tpm_transmit() so that tpm2_unseal_trusted()
can do the locking by itself.
Fixes: 0fe5480303a1 ("keys, trusted: seal/unseal with TPM 2.0 chips")
