[BusyBox] problem loading dependencies with modprobe in rc1

[William Barsse]

replying to myself ....

the previous patch is severely broken (sorry folks ...), here's another 
which fixes two other issues (plus the previous as well) with a 2.4 kernel :

- should be able to modprobe an already loaded module and get 0 return 
code :
# modprobe <something> && modprobe <something> && echo "ok" || echo "failed"
....
failed

- can't unload modules with modprobe -r :
# modprobe -r vfat
modprobe: failed to remove module vfat

Well, hope this helps and that I didn't screw up again,
- William
