staging: lustre: lnet: Replace list_for_each with list_for_each_entry
Replace use of the combination of list_for_each and list_entry
with list_for_each_entry to simplify the code and remove variables
that are used only in list_for_each.
Issue found and corrected using Coccinelle script:
@r@
expression head, member, e;
type T1, T2, T3;
iterator name list_for_each, list_for_each_entry;
identifier pos, var;
