kernel: backport yet another cosmetic ubifs patch 

On UBI-enabled devices using squashfs as their rootfs an error
message like
UBIFS error (ubi0:3 pid 1): init_constants_early: too few LEBs (12), min. is 17
was thrown while probe-mounting the rootfs which later on succeeds and
thus shouldn't alert the user.

Subject: [PATCH] ubifs: silence another error if MS_SILENT is set
To: linux-mtd@lists.infradead.org
Cc: Artem Bityutskiy <dedekind1@gmail.com>,
Richard Weinberger <richard.weinberger@gmail.com>
Probe-mounting a volume too small for UBIFS results in kernel log
polution which might irritate users.
Address this by silencing errors which may happen during boot if the
rootfs is e.g. squashfs (and thus rather small) stored on a UBI volume.
This commit should be seen in context with
commit 65fb47721925628bf85ec08c4302ac5e7224a66a
and
commit 90bea5a3f0bf680b87b90516f3c231997f4b8f3b
