[PATCH v2 2/4] KVM: nSVM: correctly restore nested_run_pending on migration

[Maxim Levitsky]

The code to store it on the migration exists, but no code was restoring it.

One of the side effects of fixing this is that L1->L2 injected events
are no longer lost when migration happens with nested run pending.
