UBI: kill debugging buffer
This patch kills the 'ubi->dbg_peb_buf' debugging buffer and the associated mutex, because all users of this buffer are now gone. We are killing this buffer because we are going to switch to dynamic debugging control, just like in UBIFS, which means that CONFIG_MTD_UBI_DEBUG_PARANOID will be removed. In this case we'd end up always allocating 'ubi->dbg_peb_buf', which is rather large (128KiB or more), and this would be wasteful. Thus, we are just killing it.
