Ed Maste 1707b4455f 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.

Note that this fix applies to the "old" ata(4) and so isn't applicable
to the default configuration in HEAD.  It is still applicable to
stable/8.
