Dongdong Liu d95f20c4f0 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: 27c1ce8bbe ("PCI/AER: Use kfifo for tracking events instead of reimplementing it")
