Commit
4f016420d368 ("Staging: lustre: obdclass: Use kasprintf") moved
some sprintf() calls earlier in the code to combine them with
memory allocation and create kasprintf() calls.
In one case, this code movement moved the sprintf to a location where the
values being formatter were different.
In particular
sprintf(niduuid, "%s_%x", mgcname, i);
was move from *after* the line
i = 0;
to a location where the value of 'i' was at least 1.
This cause the wrong name to be formatted, and triggers
CERROR("del MDC UUID %s failed: rc = %d\n",
niduuid, rc);
at unmount time.
So use '0' instead of 'i'.
