    proto.c: allow calling get_hfi_length() with a 0 byte tvb and length=-1
    
    As indicated in the comment, we allow FT_PROTOCOL, FT_NONE, FT_BYTES, FT_STRING
    and FT_STRINGZPAD to be zero-length.
    But in that case do not call tvb_ensure_captured_length_remaining() that ensures
    that at least 1 byte is  present.
