KVM: s390: vsie: Fix unshadowing while shadowing
If shadowing causes the shadow gmap to get unshadowed, exit early to
prevent an attempt to dereference the parent pointer, which at this
point is NULL.
Opportunistically add some more checks to prevent NULL parents.

Fixes: e5f98a6899bd ("KVM: s390: Add some helper functions needed for vSIE")
