headers/deps: RDMA: Optimize <rdma/rdma_netlink.h> dependencies, remove <linux/netlink.h> inclusion

          --------------------------------------------------------------------
          | Combined, preprocessed C code size of header, without line markers,
          | with comments stripped:
          -------------------------
  before: | #include <rdma/rdma_netlink.h>          | LOC:  2,231 | headers:  107
   after: | #include <rdma/rdma_netlink.h>          | LOC:    505 | headers:   26

This header is included in over 600 .c files, but doesn't actually require
the <linux/netlink.h> inclusion itself, and most of the .c files that use
it don't either.
