AHCI: Fix port reset race
bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio that is currently in flight finish. So what we do is: port reset detect ncq in flight cancel ncq delete ncq sg list at which point we have double freed the sg list. Instead, with this patch we do: port reset detect ncq in flight cancel ncq check if we are really still in flight delete ncq sg list which makes things work and gets rid of the race.
