fsdev: fix compilation with VIRTIO but not VIRTIO_9P

Browse Source 
hw/9pfs/Makefile.objs uses CONFIG_VIRTIO_9P to guard the definition for
FileOperations structs, while fsdev/Makefile.objs uses CONFIG_VIRTIO
to guard the use.  Mismatch causes linking to fail when CONFIG_VIRTIO
is set but CONFIG_VIRTIO_9P is not.

Fix it and use if/else to clarify that the two lines are for opposite
conditions.
