[server PATCH 8/8] red_channel: replace RING_FOREACH with RING_FOREACH_SAFE in some places

[Uri Lublin <uril@xxxxxxxxxx>]

This was originally intended to fix the problem fixed by
commit 53488f0275d6c8a121af49f7ac817d09ce68090d.

What is left are FOREACH loops that are at less risk and maybe safe (no
read/write or disconnect/destroy are called from within them).
