Subject: [PATCH] replace `rt_enter_critical` with `dfs_lock` for list_fd

I found that if use mutex in `rt_kprintf`,
the `rt_enter_critical` will create a assert
error later. after chehcking,I found all
operation with fd_table has using
`dfs_lock/unlock` to protect. so I think
using `dfs_lock` is enough. thanks.
