kbase: virtiofs: Clarify migration support statement

Browse Source 
virtiofs 1.11 contains support for migration so update the 'Note' which
states that migration is not supported.

Additionally mention that VM snapshots don't save state of the files
shared via virtiofs so reverting is not a good idea.

*Note:* virtiofs currently does not support migration so operations such as
migration, save/managed-save, or snapshots with memory are not supported if
a VM has a virtiofs filesystem connected.
*Note:* Older versions of ``virtiofsd`` (prior to ``1.11``) do not not support
migration so operations such as migration, save/managed-save, or snapshots with
memory may not supported if a VM has a virtiofs filesystem connected.
Additionally snapshot operations managed by libvirt do not snapshot the state
of the files shared via ``virtiofs``, and thus reverting to an earlier state is
not recommended.
