    Fix the heuristic for checking whether it's a CAM Inspector file.
    
    wtap_read_bytes() returns TRUE on *success*, so if we're in the loop,
    the last read succeeded, and no error code was supplied.  When we *exit*
    the loop, the read didn't succeed; check for the status then.  If we got
    a short read, we ran out of file data, so check the heuristics (even if
    it's not an integral number of 2-byte blocks, treat it as a CAM
    Inspector file - it might have gotten cut short); if we got a real read
    error, report that to our caller.
