Alexander Aring ff58d1c72e fs: dlm: check on minimum msglen size
[ Upstream commit 710176e836 ]

This patch adds an additional check for minimum dlm header size which is
an invalid dlm message and signals a broken stream. A msglen field cannot
be less than the dlm header size because the field is inclusive header
lengths.
