virtio: always enter drivers/virtio/
When neither VIRTIO_PCI_LIB nor VIRTIO are enabled, but the alibaba vdpa driver is, the kernel runs into a link error because the legacy virtio module never gets built: x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_features': eni_vdpa.c:(.text+0x23f): undefined reference to `vp_legacy_set_features' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_state': eni_vdpa.c:(.text+0x2fe): undefined reference to `vp_legacy_get_queue_enable' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_address': eni_vdpa.c:(.text+0x376): undefined reference to `vp_legacy_set_queue_address' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_vq_ready': eni_vdpa.c:(.text+0x3b4): undefined reference to `vp_legacy_set_queue_address' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_free_irq': eni_vdpa.c:(.text+0x460): undefined reference to `vp_legacy_queue_vector' x86_64-linux-ld: eni_vdpa.c:(.text+0x4b7): undefined reference to `vp_legacy_config_vector' x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_reset': When VIRTIO_PCI_LIB was added, it was correctly added to drivers/Makefile as well, but for the legacy module, this is missing. Solve this by always entering drivers/virtio during the build and letting its Makefile take care of the individual options, rather than having a separate line for each sub-option.
