net: kcm: kcmproc.c: Fix RCU list suspicious usage warning
This path fixes the suspicious RCU usage warning reported by
kernel test robot.
net/kcm/kcmproc.c:#RCU-list_traversed_in_non-reader_section
There is no need to use list_for_each_entry_rcu() in
kcm_stats_seq_show() as the list is always traversed under
knet->mutex held.
