From: Miao Xie <mi...@cn.fujitsu.com> _require_scratch_dev_pool() checks the devices number in SCRATCH_DEV_POOL, but it's not enough since some btrfs RAID10 tests needs 4 devices, but when 3 or less devices are provided, the check is useless and related test case will fail(btrfs/003 btrfs/011 btrfs/023).
Also _require_deletable_scratch_dev_pool only checks whether it is virtul, like virtio(not including virtio-scsi) disk will pass the check but is unable to delete. This patch enhance _require_scratch_dev_pool by add optional $1 as needed device number to do extra check. And enhance _require_deletable_scratch_dev_pool by directly check /sys/class/block/$DEV/device/delete file.
