inet: remove dead inetpeer sequence code
inetpeer sequence numbers are no longer incremented, so no need to check and flush the tree. The function that increments the sequence number was already dead code and removed in in "ipv4: remove unused function" (068a6e18). Remove the code that checks for a change, too. Verifying that v4_seq and v6_seq are never incremented and thus that flush_check compares bp->flush_seq to 0 is trivial. The second part of the change removes flush_check completely even though bp->flush_seq is exactly !0 once, at initialization. This change is correct because the time this branch is true is when bp->root == peer_avl_empty_rcu, in which the branch and inetpeer_invalidate_tree are a NOOP.
