LU-3624 utils: fix lctl test_mkdir for use in mds-survey

The mds-survey script uses the 'lctl test_mkdir' command to create
directories for metadata tests. This currently raises the following
error message:
"...stre-2.4.0/lustre/include/lustre/lustre_idl.h:683:ostid_set_id())
Bad 18446744073709551615 to set 0:0"

This patch fixes the jt_obd_md_common() routine to avoid this error
to be generated.
