Long Li 70cdd92e04 bus/vmbus: fix ring buffer mapping in secondary process
The driver code had wrong assumption that all the addresses to ring buffers
in the secondary process are the same as those in the primary process. This
is not always correct as the channels could be mapped to different
addresses in the secondary process.

Fix this by keeping track of all the mapped addresses from the primary
process in the shared uio_res, and have second process map to the same
addresses.
