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.
