[PATCH 2/3] transport-mmio: Rename QueueNum register

[Parav Pandit <parav@nvidia.com>]

Currently, the specification uses virtqueue index and number
interchangeably to refer to the virtqueue.

It is better to identify it using one terminology.

Two registers QueueNumMax and QueueNum actually reflect the queue size
or queue depth indicating max and actual number of entries in the queue.
Equivalent register in PCI transport is named differently as queue_size.

To bring consistency between pci and mmio transport, and to avoid
confusion between number and index, rename the QueueNumMax and QueueNum
registers to QueueSizeMax and QueueSize respectively.
