OvmfPkg/VirtioFsDxe: submit the FUSE_INIT request to the device

Browse Source 
Submit the FUSE_INIT request to the Virtio Filesystem device, for starting
the FUSE session.

The FUSE_INIT request is logged by the virtio-fs daemon, with this patch
applied, when (for example) using the "CONNECT" UEFI shell command.
