vfio/pci: Drop unnecessary pcibios_err_to_errno()
As of commit d97ffe236894 ("PCI: Fix return value from pci_user_{read,write}_config_*()") it's unnecessary to call pcibios_err_to_errno() to fixup the return value from these functions. pcibios_err_to_errno() already does simple passthrough of -errno values, therefore no functional change is expected.
