vDPA/ifcvf: Fix pci_read_config_byte() return code handling

vDPA/ifcvf: Fix pci_read_config_byte() return code handling

[ Upstream commit 7f8825b2a78ac392d3fbb3a2e65e56d9e39d75e9 ]

ifcvf_init_hw() uses pci_read_config_byte() that returns
PCIBIOS_* codes. The error handling, however, assumes the codes are
normal errnos because it checks for < 0.
Convert the error check to plain non-zero check.

vDPA/ifcvf: retire ifcvf_start_datapath and ifcvf_add_status

Rather than former lazy-initialization mechanism,
now the virtqueue operations and driver_features related
ops access the virtio registers directly to take
immediate actions. So ifcvf_start_datapath() should
retire.

ifcvf_add_status() is retierd because we should not change
device status by a vendor driver's decision, this driver should
only set device status which is from virito drivers
upon vdpa_ops.set_status()

ifcvf_set_driver_features(), and ifcvf_get_features()

the provisioned vDPA device features.
