f2fs: fix block_ops trace point
block operations is used to flush all dirty node and dentry blocks in the page cache and suspend ordinary writing activities, however, there are some facts such like cp error or mount read-only etc which lead to block operations can't be invoked. Current trace point print block_ops start premature even if block_ops doesn't have opportunity to execute. This patch fix it by move block_ops trace point just before block_ops.
