ipconfig: Use time_before

The functions time_before, time_before_eq, time_after, and time_after_eq
are more robust for comparing jiffies against other values.

A simplified version of the Coccinelle semantic patch making this change
is as follows:

@change@
expression E1,E2;
@@
- jiffies - E1 < E2
+ time_before(jiffies, E1+E2)
