cpumask: re-introduce cpumask_next{,_and}_wrap()

Browse source

cpumask_next_wrap_old() has two additional parameters, comparing to its
generic counterpart find_next_bit_wrap(). The reason for that is
historical.

Before 4fe49b3b97c262 ("lib/bitmap: introduce for_each_set_bit_wrap()
macro"), cpumask_next_wrap() was used to implement for_each_cpu_wrap()
iterator. Now that the iterator is an alias to generic
for_each_set_bit_wrap(), the additional parameters aren't used and may
confuse readers.

All existing users call cpumask_next_wrap() in a way that makes it
possible to turn it to straight and simple alias to find_next_bit_wrap().

In a couple of places kernel users opencode missing cpumask_next_and_wrap().
Add it as well.
