[PATCH 5.12 157/296] mptcp: avoid error message on infinite mapping

From: Paolo Abeni <pabeni@redhat.com>

commit 3ed0a585bfadb6bd7080f11184adbc9edcce7dbc upstream.

Another left-over. Avoid flooding dmesg with useless text,
we already have a MIB for that event.

Fixes: 648ef4b88673 ("mptcp: Implement MPTCP receive path")
