[PATCH] ubifs: Fix WARN_ON logic in exit path

[Richard Weinberger <richard@xxxxxx>]

ubifs_assert() is not WARN_ON(), so we have to invert
the checks.
Randy faced this warning with UBIFS being a module, since
most users use UBIFS as builtin because UBIFS is the rootfs
nobody noticed so far. :-(
Including me.

Reported-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
Fixes: 54169ddd382d ("ubifs: Turn two ubifs_assert() into a WARN_ON()")
Signed-off-by: Richard Weinberger <richard@xxxxxx>

Greg,

can you please take this patch directly?
It fixes a brown paper bug which was introduced in rc1, I'd like to avoid
having it in a release and going the -stable path.

Thanks,
//richard
