[PATCH] net: kcm: kcmproc.c: Fix RCU list suspicious usage warning

[madhuparnabhowmik10]

From: Madhuparna Bhowmik <madhuparnabhowmik10@xxxxxxxxx>

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.
