Artem Bityutskiy c88ac00c5a UBIFS: fix assertion warnings
This patch fixes UBIFS assertion warnings like:

UBIFS assert failed in ubifs_leb_unmap at 135 (pid 29365)
Pid: 29365, comm: integck Tainted: G          I 2.6.37-ubi-2.6+ #34

They happen when we re-mount from R/O mode to R/W mode. While
re-mounting, we write to the media, but we still have the c->ro_mount
flag set. The fix is very simple - just clear the flag before
starting re-mounting R/W.

These warnings are caused by the following commit:
2ef13294d2

For -stable guys: this bug was introduced in 2.6.38, this is materieal
for 2.6.38-stable.
