The tests mount the second device in the device pool but never
unmount it, causing the next test to fail.
Example:
$ cat local.config
export TEST_DEV=/dev/sdb
export TEST_DIR=/home/fdmanana/btrfs-tests/dev
export SCRATCH_MNT="/home/fdmanana/btrfs-tests/scratch_1"
export SCRATCH_DEV_POOL="/dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg"
export FSTYP=btrfs
$ ./check btrfs/125 btrfs/126

The test does the following:
Initialize a RAID1 with some data
Re-mount RAID1 degraded with _dev1_ and write up to
half of the FS capacity
Save md5sum checkpoint1
Re-mount healthy RAID1
Let balance re-silver.
Save md5sum checkpoint2
Re-mount RAID1 degraded with _dev2_
Save md5sum checkpoint3
Verify if all three md5sum match
