[PATCH 2/2] EDAC/igen6: Convert PCIBIOS_* return codes to errnos

[Ilpo Järvinen]

errcmd_enable_error_reporting() uses pci_{read,write}_config_word()
that return PCIBIOS_* codes. The return code is then returned all the
way into the probe function igen6_probe() that returns it as is. The
probe functions, however, should return normal errnos.

Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it from errcmd_enable_error_reporting().
