vfs: fix spinning prevention in prune_icache_sb
We need to move the inode to the end of the list to actually make the spinning prevention explained in the comment above it work. With a plain list_move it will simply stay in place as we're always reclaiming from the head of the list. Signed-off-by: Christoph Hellwig <hch@lst.de>
