piaojun edcd9d9773 net/9p/trans_virtio.c: add null terminal for mount tag ...

chan->tag is Non-null terminated which will result in printing messy code
when debugging code. So we should add '\0' for tag to make the code more
convenient and robust. In addition, I drop char->tag_len to simplify the
code.
