sd-netlink: remove unused RTNL_WQUEUE_MAX define

While investigating why some of my netlink calls would timeout I
stumbled upon the definition of the max write queue length. Finding this
constant made me believe we still had a write queue in the code - which
isn't true. The netlink write queue code was removed in #189.
