Removed unneeded "count" variable in utmpdump.c.

Browse Source 
Fixed typo in accidental wrote_wtmp_rlevel == 0 || wrote_wtmp_rlevel
comparison so the latter is wrote_utmp_rlevel.

Simplified logic in mountpoint.c when testing for same device or same inode.

Thanks to David Binderman for pointing out the above three issues.
