net: page_pool: rename page_pool_is_last_ref()
page_pool_is_last_ref() releases a reference while the name,
to me at least, suggests it just checks if the refcount is 1.
The semantics of the function are the same as those of
atomic_dec_and_test() and refcount_dec_and_test(), so just
use the _and_test() suffix.
