Subject: [PATCH] LU-9420 lnd: Remove a bad check which slipped in
When the patch for LU-5710 landed, a check for message size was landed
that should not have been. This check was part of a patch in LU-7650
which was later pulled because it broke things. LU-5718 picked up this
code via its many rebases (it too forever to land LU-5718 which is the
core problem here).
This patch removes that messaage size check.
