[PATCH v2 2/8] PCI: Cleanup struct aer_err_info

[Naveen Naidu]

The id, status and the mask fields of the struct aer_err_info comes
directly from the registers, hence their sizes should be explicit.

The length of these registers are:
  - id: 16 bits - Represents the Error Source Requester ID
  - status: 32 bits - COR/UNCOR Error Status
  - mask: 32 bits - COR/UNCOR Error Mask

Since the length of the above registers are even, use u16 and u32
to represent their values.

Also remove the __pad fields.

"pahole" was run on the modified struct aer_err_info and the size
remains unchanged.
