The logic for invoking the validation of the TPM 1.2 state was
broken. The validation of volatile and save state state requires
that the permanent state is available, so we always load it
first.

Implement TPMLIB_ValidateState(), which is supposed to be used
for checking usability of state blobs before TPMLIB_MainInit()
is called or TPM_Startup has been sent to the TPM.
This function is useful to be called once TPM state blobs
have been migrated to a destination and we need to check
whether libtpms can use these state blobs and if not
we have a chance to fall back to the migration source host.
