Brijesh Singh b0338c5329 OvmfPkg/VirtioLib: alloc VRING buffer with AllocateSharedPages()
The VRING buffer is a communication area between guest and hypervisor.
Allocate it using VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages() so that
it can be mapped later with VirtioRingMap() for bi-directional access.
