tpm12: Fix yet some more -O3 compilation errors (Trusty)

Browse Source 
This patch addresses the following false positives on Ubuntu Trusty
on x86_64:

tpm12/tpm_process.c: In function ?TPM_Process_GetCapability?:
tpm12/tpm_process.c:3521:35: error: ?transportEncrypt? may be used uninitialized in this function [-Werror=maybe-uninitialized]
      returnCode = TPM_ProcessAudit(tpm_state,
                                   ^

tpm12/tpm_counter.c: In function ?TPM_Process_IncrementCounter?:
tpm12/tpm_counter.c:421:27: error: ?counterValue? may be used uninitialized in this function [-Werror=maybe-uninitialized]
  rc = TPM_Sbuffer_Append32(sbuffer, tpm_counter_value->counter);
                           ^
tpm12/tpm_counter.c:791:24: note: ?counterValue? was declared here
     TPM_COUNTER_VALUE *counterValue; /* The counter value */
                        ^

tpm12/tpm_key.c: In function ?TPM_KeyParms_CheckProperties?:
tpm12/tpm_key.c:1959:42: error: ?tpm_rsa_key_parms? may be used uninitialized in this function [-Werror=maybe-uninitialized]
   rc = TPM_KeyParams_CheckDefaultExponent(&(tpm_rsa_key_parms->exponent));
