Yang Chi 0e6a998e05 Fix QUIC EOF sending when DSR is used ...

Summary:
This is a bug fix. When a stream finished sending all it's BufMetas, it can
send EOF from frontend QUIC host. In that case, it will use
currentWriteOffset value which is wrong.

This diff changes it so that (1) frontend can only write FIN only frame if
writeBufMeta's offset is <= finalWriteOffset; (2) When it writes such frame
it will use finalWriteOffset as the offset value in the frame.
