[PATCH 30/49] ixgbe: replace bitmap_weight with bitmap_weight_eq

[Yury Norov]

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