ath6kl: list_first_entry() is never NULL
We can remove the NULL check here. It triggers a Smatch warning because
list_first_entry() never is NULL and people who check for it normally
intend to check for list_empty() instead. In these cases however,
we've already verified that the lists are not empty.
