Claudio Imbrenda b4414fbc0f KVM: s390: extend kvm_s390_shadow_fault to return entry pointer

commit 5ac14bac08ae827b619f21bcceaaac3b8c497e31 upstream.

Extend kvm_s390_shadow_fault to return the pointer to the valid leaf
DAT table entry, or to the invalid entry.

Also return some flags in the lower bits of the address:
PEI_DAT_PROT: indicates that DAT protection applies because of the
              protection bit in the segment (or, if EDAT, region) tables.
PEI_NOT_PTE: indicates that the address of the DAT table entry returned
             does not refer to a PTE, but to a segment or region table.
