[net-next 2/2] tipc: simplify small window members' sorting algorithm

[Jon Maloy <jon.maloy@ericsson.com>]

We simplify the sorting algorithm in tipc_update_member(). We also make
the remaining conditional call to this function unconditional, since the
same condition now is tested for inside the said function.
