PCI/AER: Initialize aer_fifo
Previously we did not call INIT_KFIFO() for aer_fifo. This leads to
kfifo_put() sometimes returning 0 (queue full) when in fact it is not.
It is easy to reproduce the problem by using aer-inject:
$ aer-inject -s :82:00.0 multiple-corr-nonfatal
The content of the multiple-corr-nonfatal file is as below:
AER
COR RCVR
HL 0 1 2 3
AER
UNCOR POISON_TLP
HL 4 5 6 7
Fixes: 27c1ce8bbed7 ("PCI/AER: Use kfifo for tracking events instead of reimplementing it")
