Don't import library guestfs directly
Don't import library guestfs directly

Library guestfs is not in requirements file, but is imported directly
in nova/virt/disk/vfs/guestfs.py. That conflicts with global variable
guestfs, leads out one more time import and shadow issue, so remove it
from import group.
