[PATCH][2.6.0-test8] fix new initrd with devfs

[Andrey Borzenkov]

If devfs is mounted on boot initrd does not work. devfs does not allow 
creation of files other than device and symlink. Now when initrd is no more 
device there is no reason to create it in /dev either. The patch simply 
changes /dev/initrd -> /initrd.img. I do not insist on this name :)
