[PATCH V4 net-next 1/3] virtio: rename virtio_config_enabled to virtio_config_core_enabled

From: Jason Wang
Date: Tue Jul 30 2024 - 23:00:53 EST


Following patch will allow the config interrupt to be disabled by a
specific driver via another boolean. So this patch renames
virtio_config_enabled and relevant helpers to
virtio_config_core_enabled.
