[BusyBox] Serious bug in find_mount_point.c

Hi,

Has anyone noticed that:

$ df {path}

does not output anything but the header line if {path} is on the
root filesystem or denotes the root device?

I've attached a fix for that.
Since df skips over the rootfs, we have to insure that find_mount_point
will will too.

With this patch both 'df /' and 'df /dev/root' work properly.
This is more than can be said for the "standard" linux df command.

$ df /dev/root
Filesystem           1K-blocks      Used Available Use% Mounted on
none                         0         0         0   -  /dev

Should busybox folks file a bug with df's maintainers, or conform to its 
breakage? ;-)
