[PATCH] ubifs: add update vfs super block infomation when remount to ro mode

[Zhang JieJing]

(resend since HTML mail rejected by linux-fsdevel.)
Hi Artem,

I just clone the  git://git.infradead.org/ubifs-2.6.git, and git am my
patch, It is very clean patched, so, maybe your git repo code is very
new, so the patch can't cleaned apply.

This is my first patch give back to upstream, even I read the kernel
document 'how-to send patch' but still something leaked.
If I did something wrong, Please show me the right way or something like that,
Thanks for your time.

Best regards,
Zhang Jiejing
