KVM: s390: vsie: Fix race in walk_guest_tables()
It is possible that walk_guest_tables() is called on a shadow gmap that
has been removed already, in which case its parent will be NULL.
In such case, return -EAGAIN and let the callers deal with it.
Fixes: e38c884df921 ("KVM: s390: Switch to new gmap")
