[PATCH net-next v5 09/18] qed: Use dedicated list iterator variable

[Jakob Koschel <jakobkoschel@gmail.com>]

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable [1].
