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.
