octeontx2-pf: replace bitmap_weight with bitmap_empty where appropriate
In some places, octeontx2 code calls bitmap_weight() to check if any bit of
a given bitmap is set. It's better to use bitmap_empty() in that case
because bitmap_empty() stops traversing the bitmap as soon as it finds
first set bit, while bitmap_weight() counts all bits unconditionally.
