UBIFS: fix a rare memory leak in ro to rw remounting path

commit eaeee242c531cd4b0a4a46e8b5dd7ef504380c42 upstream.

When re-mounting from R/O mode to R/W mode and the LEB count in the superblock
is not up-to date, because for the underlying UBI volume became larger, we
re-write the superblock. We allocate RAM for these purposes, but never free it.
So this is a memory leak, although very rare one.
