[BusyBox] bug#1207: route del: seg faults

[Jaspreet Singh]

Package: busybox
Version: 0.60

When I invoke route del it results in a segmentation fault.

Also when routes are deleted the entries are shown. 

I am submitting a patch with fixes the above 2 problems. The patch
ignores any routes with no "U" flags.
