similar to: [PATCH v2 -next] vdpa: remove unused variables 'ifcvf' and 'ifcvf_lm'

This commit implements a new function ifcvf_get_driver_feature() which read driver_features from virtio registers. To be less ambiguous, ifcvf_set_features() is renamed to ifcvf_set_driver_features(), and ifcvf_get_features() is renamed to ifcvf_get_dev_features() which returns the provisioned vDPA device features.

Formerly, ifcvf driver has implemented a lazy-initialization mechanism for the virtqueues and other config space contents, it would store all configurations that passed down from the userspace, then load them to the device config space upon DRIVER_OK. This can not serve live migration, so this series implement an immediate initialization mechanism, which means rather than the former store-load
