kvm: rename last argument to kvm_get_dirty_log_protect
When manual dirty log reprotect will be enabled, kvm_get_dirty_log_protect's pointer argument will always be false on exit, because no TLB flush is needed until the manual re-protection operation. Rename it from "is_dirty" to "flush", which more accurately tells the caller what they have to do with it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
