LU-11186 ofd: fix for a final oid at sequence

LU-11186 ofd: fix for a final oid at sequence

There was an error at the end of sequence range and last oid
0xffffffff can't be created. The 0xffffffff is a valid oid, and
sequence update happens only if it is created.

LustreError: 11756:0:(ofd_objects.c:217:ofd_precreate_objects())
lustre-OST0000:0xfffffffe:10737419264 hit the OBIF_MAX_OID (1<<32)!
LustreError: 11756:0:(ofd_dev.c:1764:ofd_create_hdl())
lustre-OST0000: unable to precreate: rc = -28

The patch fixes this error.

The conf-sanity 122 is added for checking sequence update.
