Initialize v2r1 ddquot padding in dump
v2r1_mem2diskdqblk() that writes quota structure into memory block
calls tree_entry_unused() to decide the structure is in use (and
rewrites UID then). However tree_entry_unused() scan can be spoiled
because padding is not initialized and contains random value.
