Every call to _scratch_dev_pool_get must be paired with call to
_scratch_dev_pool_put otherwise the SCRATCH_POOL variable will have
less devices than it actually must.

btrfs/125, btrfs/148, btrfs/157, and btrfs/158 test for raid56

them.

Test that a direct IO write works against raid5/6 filesystems and that
after the write operation we are able to read back the correct data
and scrub operations don't find any errors.
This test is motivated by a regression introduced in the merge window
for the 4.13 linux kernel, which was undetected by the current set of
test cases. The issue is fixed by the following patch:
"Btrfs: fix write corruption due to bio cloning on raid5/6"
