aer_print_error() skips printing if ratelimit_print[i] is not set. In the
native AER path, ratelimit_print is initialized by add_error_device()
during source device discovery, and is set to 1 for fatal errors to bypass
rate limiting since fatal errors should always be logged.
The DPC/EDR path uses the DPC-capable port as the error source and reads
its AER uncorrectable error status registers directly in
dpc_get_aer_uncorrect_severity(). Since it does not go through
add_error_device(), ratelimit_print[0] is left uninitialized and zero. As
a result, aer_print_error() silently drops all AER error messages for
DPC/EDR triggered events.
Set ratelimit_print[0] to 1 to bypass rate limiting and always print AER
logs for uncorrectable errors detected by the DPC port.
