[VZDQ] forced accounting for vzquota vzquota in GFS is implemented differently of one for ext3. Instead of atomic check-and-account, it makes checking first and, if at least one block can be added, it starts transaction, which makes strict accounting. We need two new methods: 1. Forced accounting is implemented by passing a special value to alloc_space. 2. Quota checking also can be done in this way, but for now it is implemnted as check-and-account for 1 block and immediately free it. No modifications to vzquota core required
