Claudio Imbrenda 3ffe5eb4a5 KVM: s390: vsie: Fix races with partial gmap invalidations 
Introduce a new boolean flag, used for shadow gmaps, to keep track of
whether the gmap has been invalidated, either partially or totally.

Use the new flag to check whether shadow gmap invalidations happened
during shadowing. In such cases, abort whatever was going on, return
-EAGAIN and let the caller try again.

Fixes: 19d6c5b804 ("KVM: s390: vsie: Fix unshadowing while shadowing")
