qemu-options.hx: 9p: clarify -virtfs vs. -fsdev 



The docs are ambiguous about the difference (or actually their
equality) between options '-virtfs' vs. '-fsdev'. So clarify that
'-virtfs' is actually just a convenience shortcut for its
generalized form '-fsdev' in conjunction with '-device virtio-9p-pci'.

And as we're at it, also be a bit more descriptive what 9pfs is
actually used for.

    Define a new filesystem device and expose it to the guest using a

    virtio-9p-device. The general form of a Virtual File system

    pass-through options are:

    Define a new virtual filesystem device and expose it to the guest using

    a virtio-9p-device (a.k.a. 9pfs), which essentially means that a certain

    directory on host is made directly accessible by guest as a pass-through

    file system by using the 9P network protocol for communication between

    host and guests, if desired even accessible, shared by several guests

    simultaniously.



    Note that ``-virtfs`` is actually just a convenience shortcut for its

    generalized form ``-fsdev -device virtio-9p-pci``.



    The general form of pass-through file system options are:



    ``local``

        Accesses to the filesystem are done by QEMU.
