ifcvf/vDPA: fix misuse virtio-net device config size for blk dev

Browse source

This commit fixes a misuse of virtio-net device config size issue
for virtio-block devices.

A new member config_size in struct ifcvf_hw is introduced and would
be initialized through vdpa_dev_add() to record correct device
config size.

To be more generic, rename ifcvf_hw.net_config to ifcvf_hw.dev_config,
the helpers ifcvf_read/write_net_config() to ifcvf_read/write_dev_config()
