PCI, AER: Fix severity usage in aer trace event

There's inconsistency between dmesg and the trace event output.
When dmesg says "severity=Corrected", the trace event says
"severity=Fatal". What happens is that HW_EVENT_ERR_CORRECTED is
defined in edac.h:

enum hw_event_mc_err_type {
        HW_EVENT_ERR_CORRECTED,
        HW_EVENT_ERR_UNCORRECTED,
        HW_EVENT_ERR_FATAL,
        HW_EVENT_ERR_INFO,
};

while aer_print_error() uses aer_error_severity_string[] defined as:

static const char *aer_error_severity_string[] = {
        "Uncorrected (Non-Fatal)",
        "Uncorrected (Fatal)",
        "Corrected"
};

In this case dmesg is correct because info->severity is assigned in
aer_isr_one_error() using the definitions in include/linux/ras.h:
