qed: replace bitmap_weight with bitmap_empty in qed_roce_stop()

Browse Source 
qed_roce_stop() calls bitmap_weight() to check if any bit of a given
bitmap is set. We can do it more efficiently with bitmap_empty() because
bitmap_empty() stops traversing the bitmap as soon as it finds first set
bit, while bitmap_weight() counts all bits unconditionally.
