bitops: rename for_each_set_bit_cont() in favor of analogous list.h function

This renames for_each_set_bit_cont() to for_each_set_bit_from() because
it is analogous to list_for_each_entry_from() in list.h rather than
list_for_each_entry_continue().

This doesn't remove for_each_set_bit_cont() for now.
