Subject: [PATCH v14 15/34] PCI/AER: Update struct aer_err_info with kernel-doc formatting

Update the existing 'struct aer_err_info' definition to use kernel-doc
formatting. Remove the inline comments to reduce noise and do not introduce
functional changes. This will improve readability and maintainability.
