Subject: [PATCH 5.11 021/104] RDMA/rtrs: Do not signal for heatbeat

From: Jack Wang <jinpu.wang@...ud.ionos.com>

commit b38041d50add1c881fbc60eb2be93b58fc58ea21 upstream.

For HB, there is no need to generate signal for completion.

Also remove a comment accordingly.

Fixes: c0894b3ea69d ("RDMA/rtrs: core: lib functions shared between client and server modules")
