[PATCH v2 3/7] KVM: selftests: Mark correct page as mapped in virt_map()

[Oliver Upton]

The loop marks vaddr as mapped after incrementing it by page size,
thereby marking the *next* page as mapped. Set the bit in vpages_mapped
first instead.

Fixes: 56fc7732031d ("KVM: selftests: Fill in vm->vpages_mapped bitmap in virt_map() too")
