The AER service driver's aer_get_device_err_info() function does not
read uncorrectable (UCE) fatal error status from PCIe upstream port
devices. As a result, fatal errors are not logged or handled as needed
for CXL PCIe upstream switch port devices.
Update the aer_get_device_err_info() function to read the UCE fatal
status for all CXL PCIe port devices.
The fatal error status will be used in future patches implementing
CXL PCIe port error handling and logging.
