ipvs: unify the formula to estimate the overhead of processing connections

Browse Source 
lc and wlc use the same formula, but lblc and lblcr use another one. There
is no reason for using two different formulas for the lc variants.

The formula used by lc is used by all the lc variants in this patch.
