  Log:
  Fix an amd64 issue I overlooked. When setting up a callout to
  ndis_timercall() in NdisMInitializeTimer(), we can't use the raw
  function pointer. This is because ntoskrnl_run_dpc() expects to
  invoke a function with Microsoft calling conventions. On i386,
  this works because ndis_timercall() is declared with the __stdcall
  attribute, but this is a no-op on amd64. To do it correctly, we
  have to generate a wrapper for ndis_timercall() and us the wrapper
  instead of of the raw function pointer.
  
  Fix this by adding ndis_timercall() to the funcptr table in subr_ndis.c,
  and create ndis_findwrap() to extract the wrapped function from the
  table in NdisMInitializeTimer() instead of just passing ndis_timercall()
  to KeInitializeDpc() directly.
