MFC r231573:

  Fix panic after "WARNING - ATA_IDENTIFY taskqueue timeout"

  When performing a firmware upgrade via atacontrol[1] the subsequent
  command may time out producing the error message above.  When this
  happens the callout could still be active, and the system would then
  panic due to a destroyed semaphore.

  Instead, ensure that the callout is done first, via callout_drain.
