btrfs/150: add _scratch_dev_pool_get/put to run the test as expected

btrfs/150 uses RAID1 profile and make SCRATCH_DEV fail for test.
However, if SCRATCH_DEV_POOL consists more than two devices,
SCRATCH_DEV may not be used for RAID1 pair and the tests may not run
as expected.

Fix this by add _scratch_dev_pool_get/put like other tests (141, 143
etc.) do.
