LU-16455 tests: recovery-small test_139() fix

mds device calculated before stop () can not be used
after stop() because of a device-mapper device is removed and
facet device is restored:
  stop () ->
    elif dm_flakey_supported $facet; then
      if [[ -n ${!failover_host} &&
               ${!failover_host} != ${!host} ]]
         dm_cleanup_dev $facet ->
               unexport_dm_dev $facet

Without this fix test_139 fails on failover setup:
  losetup: /dev/mapper/mds1_flakey: failed to set up loop device:
    No such file or directory

To reproduce the failure just run:
  sh llmountcleanup.sh
  ONLY=139 sh recovery-small.sh
on failover setup where mds1_HOST != mds1failover_HOST
