Subject: [patch -next] qla2xxx: list cursors are not null
This is just a cleanup.
The unneeded NULL check annoys static checkers because we already
derefenced it and the we check it and then (if it's not the _safe()
version) we dereference it again without checking. And the static
checker is all, "Wah? Is it null or not?"
