af_decnet: Use time_after_eq
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,E3;
@@
- jiffies - E1 >= (E2*E3)
+ time_after_eq(jiffies, E1+E2*E3)
