Selva Nair a10564c716 Cleanup: Close duplicated handles in interactive service
Several handles from openvpn.exe are duplicated in the
service for registering ring buffer memory maps with the
driver. These handles are not required after registration,
as all access is through handles in openvpn.exe. Only the
map base address (send_ring, rceive_ring) need be retained
for later unmapping.

Use local variables for duplicated handles and close them
soon after use.

The struct ring_buffer_handles_t is renamed to ring_buffer_maps_t
as there are no handles in there any longer.
