s3: Safely mark our sconn as smb2 if we have that protocol

Otherwise smbd will crash at an unclean exit. Without this conn_close_all will
do a close_cnum() on all connection_struct's. In smb2, those are talloc
children of the smbd_smb2_tcon's. sconn is talloc_free'ed after the
conn_close_all, but the smbd_smb2_tcon destructor will still reference
tcon->compat_conn, referencing then free'ed (and null'ed out) memory.
