[netdrvr sk_mca] remove ancient-kernel compat code; fix bugs

* removed ancient-kernel compat code from sk_mca.h.  I leave
  it to janitors to remove the now-useless SKMCA_xxx wrappers.
* removed ancient-kernel compat code from sk_mca.c.
* s/SKMCA_NETDEV/net_device/
* fixed static net_device initialization (this will go away
  when dynamic-alloc patches land)
