Description

mount_mds_client() / umount_mds_client() defect:

mount/umount client is to be executed on active facet/host, not on mds1_HOST. Without this fix test_140a() fails on failover setup:
CMD: lm0101 umount /mnt/lustre2 2>&1
CMD: lm0102 rmdir /mnt/lustre2
lm0102: rmdir: failed to remove '/mnt/lustre2':
No such file or directory
test_140a: FAIL: no clients with recovery disabled

To reproduce the failure just run:
ONLY="107 140a" sh recovery-small.sh
on failover setup where mds1_HOST != mds1failover_HOST.

Fixes: 8bd04b4e57 ("LU-12722 target: disable recovery for local clients")
