[PATCH v2 02/13] vtpmmgr: Print error code to aid debugging

[Jason Andryuk <jandryuk@gmail.com>]

tpm_get_error_name returns "Unknown Error Code" when an error string
is not defined.  In that case, we should print the Error Code so it can
be looked up offline.  tpm_get_error_name returns a const string, so
just have the two callers always print the error code so it is always
available.
