AsyncConnection: Fix connection doesn't exchange in_seq problem

1. osd.a connect to osd.b and osd.b try to connect a
2. osd.b got WAIT then osd.b accpet connection from osd.a
2. osd.b inject error cause each side connection try to reconnect, connect_seq++
3. osd.a try to reconnect
4. osd.b connect to osd.a and cause the new accept connection try to replace
5. osd.b's is_reset_from_peer=true
6. inject error to osd.b
7. osd.b connect to osd.a
8. successfully and is_reset_from_peer still is true
9. long time passed
10. error happen and osd.a connect to osd.b
11. because is_reset_from_peer is true, they don't exchange in_seq
