[PATCH] ubifs: Remove uncallable debug code

[linux at treblig.org]

From: "Dr. David Alan Gilbert" <linux at treblig.org>

ubifs_dump_budget_req() and ubifs_dump_index() have been unused
since they were originally added back in 2008's
commit 1e51764a3c2a ("UBIFS: add new flash file system")

They were renamed from dbg_dump_budget_req() and dbg_dump_index() in
2012.

Remove them.
