x86/platform/iosf_mbi: Convert PCIBIOS_* return codes to errnos
[ Upstream commit 7821fa101eab529521aa4b724bf708149d70820c ]
iosf_mbi_pci_{read,write}_mdr() use pci_{read,write}_config_dword()
that return PCIBIOS_* codes but functions also return -ENODEV which are
not compatible error codes. As neither of the functions are related to
PCI read/write functions, they should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it.
