Fix assertion. I haven't tested it fully (I can't reproduce Lisa's error) but I believe it should fix what she's running into (which was definitely a bug).

src/cpu/o3/fetch_impl.hh:
    Move assertion to area where it should really always be true.  Sometimes you might recvRetry and not necessarily be blocked (if there was a squash).
