PCI: aerdrv: redefine PCI_ERR_ROOT_*_SRC

The Error Source Identification Register (Offset 34h) is 4 byte
which contains a couple of 2 byte field, "[15:0] ERR_COR Source
Identification" and "[31:16] ERR_FATAL/NONFATAL Source Identification."

This patch defines PCI_ERR_ROOT_ERR_SRC to make dword access sensible.
