tpm: don't print error message in tpm_transmit_cmd when tpm still testing 

Currently tpm_transmit_cmd will print an error message if the tpm
returns something other than TPM2_RC_SUCCESS. This means that if the
tpm returns that it is testing an error message will be printed, and
this can cause confusion for the end user. So avoid printing the error
message if TPM2_RC_TESTING is the return code.
