Many test cases use local variables to manage the names of each device in
SCRATCH_DEV_POOL. Let _scratch_dev_pool_get set an array, SCRATCH_DEV_NAME,
for it.
Usage:
_scratch_dev_pool_get <n>
# device names are in the array SCRATCH_DEV_NAME.
${SCRATCH_DEV_NAME[0]} ${SCRATCH_DEV_NAME[1]} ...
_scratch_dev_pool_put
