Subject: [PATCH v2 1/8] PCI/AER: Remove ID from aer_agent_string[]

Before 010caed4ccb6 ("PCI/AER: Decode Error Source RequesterID")
the AER error logs looked like:

  pcieport 0000:00:03.0: AER: Corrected error received: id=0018
  pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0018 (Receiver ID)
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP

In 010caed4ccb6 ("PCI/AER: Decode Error Source Requester ID"),
the "id" field was removed from the AER error logs, so currently AER
logs look like:

  pcieport 0000:00:03.0: AER: Corrected error received: 0000:00:03:0
  pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP

The second line in the above logs prints "(Receiver ID)", even when
there is no "id" in the log line. This is confusing.

Remove the "ID" from the aer_agent_string[]. The error logs will
look as follows (Sample from dummy error injected by aer-inject):

  pcieport 0000:00:03.0: AER: Corrected error received: 0000:00:03.0
  pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver)
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP
