[PATCH 31/49] octeontx2-pf: replace bitmap_weight with bitmap_weight_{eq,gt}

[Yury Norov]

OcteonTX2 code calls bitmap_weight() to compare the weight of bitmap with
a given number. We can do it more efficiently with bitmap_weight_{eq,gt}
because conditional bitmap_weight may stop traversing the bitmap earlier,
as soon as condition is (or can't be) met.
