vDPA/ifcvf: Fix pci_read_config_byte() return code handling

Browse source

[ Upstream commit 7f8825b2a7 ]

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.
