ata qc timeout messages should also print the timeout duration

Issue

• When a HDD on an AHCI controller is starting to fail, the following kernel messages may be observed:

  66192 [Wed Apr  1 13:37:59 2020] ata1.00: qc timeout (cmd 0xef)
  66193 [Wed Apr  1 13:37:59 2020] ata1.00: failed to set xfermode (err_mask=0x4)
  66194 [Wed Apr  1 13:37:59 2020] ata1: hard resetting link
  

• The qc timeout message does not display the actual duration of the timeout.

• It is valuable to see how long the timeouts are in order to further diagnose problems.
