wolfSSL_Rehandshake(): don't set 'ret' unless HAVE_SESSION_TICKET
defined (otherwise compiler will complain:  warning: Value stored to
'ret' is never read)

AES GCM streaming: fix 64-bit word version to compile and pass testing
Use '--enable-aesgcm=word' to get the word32 or word64 implementation
depending on the availabilty of 64-bit type.
