staging: lustre: obd_mount: use correct niduuid suffix.
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'.
