[PATCH] UBIFS: free budget in delete_inode as well

[Artem Bityutskiy <dedekind@infradead.org>]

From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Although the inode is marked as clean when it is being deleted,
it might stay and be used as orphan, and be marked as dirty.
So we have to free the budget when we delete it.
