Correctly handle the return value from EVP_Cipher() in the CMAC code
EVP_Cipher() is a very low level routine that directly calls the
underlying cipher function. It's return value semantics are very odd.
Depending on the type of cipher 0 or -1 is returned on error. We should
just check for <=0 for a failure.
Fixes #11957
