file was not migrated to pool testpool

Test session details:
clients: https://build.whamcloud.com/job/lustre-reviews/95735 - 4.18.0-425.10.1.el8_7.x86_64
servers: https://build.whamcloud.com/job/lustre-reviews/95735 - 4.18.0-425.10.1.el8_lustre.x86_64

the utility lfs_migrate seems not working when root is set with PFL layout and it doesn't return any error
