[PATCH v5 1/5] PCI/AER: Remove ID from aer_agent_string[]

[Naveen Naidu]

Currently, we do not print the "id" field in the AER error logs. Yet the
aer_agent_string[] has the word "id" in it. The AER error log looks
like:

  pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)

Without the "id" field in the error log, The aer_agent_string[]
(eg: "Receiver ID") does not make sense. A user reading the
aer_agent_string[] in the log, might inadvertently look for an "id"
field and not finding it might lead to confusion.

Remove the "ID" from the aer_agent_string[].

It is easy to reproduce this by using aer-inject:

  $ aer-inject -s 00:03:0 corr-err-file

The content of the corr-err-file file is as below:

  AER
  COR_STATUS BAD_TLP
  HEADER_LOG 0 1 2 3

The following are sample dummy errors inject via aer-inject.

Before
=======

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) <--- no id field
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP

After
======

  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
