With changes introduced in 667308dd97bf41382d4ab299fa5b56c235cfeb27
it is no longer possible to use SCRATCH_DEV_POOL variable because of
error:
common/config: Error: $SCRATCH_DEV should be unset when
$SCRATCH_DEV_POOL is set
This was because get_next_config() would get called twice and hence it
would complain on the second run that SCRATCH_DEV is already set. Fix
it by making sure that we call get_next_config() only once if there
are no sections in the config file.
Also make sure that we export SCRATCH_DEV in the case we're deducing it
from SCRATCH_DEV_POOL.
