mm: memcontrol: simplify value comparison between count and limit

Browse source

When the variables count and limit have the same value(count == limit),
the result of min(margin, limit - count) statement should be 0 and the
variable margin is set to 0.  So in this case, the min() statement is
not necessary and we can directly set the variable margin to 0.
