f2fs: remove struct victim_selection default_v_ops

Browse Source 
There is only single instance of these ops, and Jaegeuk point out that:

    Originally this was intended to give a chance to provide other
    allocation option. Anyway, it seems quit hard to do it anymore.

So remove the indirection and call f2fs_get_victim() directly.
