Some SED Opal compliant NVMe drives generate "empty atoms" that cause
the message response parser to fail. The TCG spec indicates that 
empty atoms are for alignment and should be ignored. This change
adds recognition of empty atoms and ignores them if found. This
allows the parser to corectly process the response message.
