[PATCH 03/13] KVM: nSVM: rename nested_sync_control_from_vmcb02 to nested_sync_int_ctl_from_vmcb02

[Maxim Levitsky <mlevitsk@redhat.com>]

The nested_sync_control_from_vmcb02 name is misleading as there
are many fields which are modified by the CPU and need to be written back
to vmcb12.

This function only copies some int_ctl bits and thecevent_inj*
fields.

Make it copy only these int_ctl bits and rename the function.
