KEYS, trusted: a bunch of bug fixes

This patch set contains a bunch of disjoint bug fixes.

v4:
* Do not create stubs for tpm_transmit_cmd(), tpm_try_get_ops() and tpm_put_ops().

v3:
* Reordered patches a bit, i.e. trivial fixes in the head and the least trivial in the tail.
<no xref>
* Added the missing "return -ENODEV;" to tpm_transmit_cmd(), when the kernel is compiled without TPM support.
