[PATCH 12/19] qemu-kvm: Drop some obsolete/unused fields from kvm_context

[Jan Kiszka <jan.kiszka@xxxxxx>]

From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

irqchip_in_kernel cam be migrated to the field in KVMState, and opaque
as well as dirty_pages_log_all were write-only.

Signed-off-by: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>
