[patch 3/4] uml: remove most devfs_mk_symlink calls

[blaisorblade_spam]

Cc: Christoph Hellwig <hch@xxxxxxxxxxxxx>

Remove uses of devfs_mk_symlink().

We didn't do this before to avoid breaking most user setups, but this patch
should be quite harmless.

I've excluded the hottest part, i.e. the ubd symlink, while removing the
other; I released a end-user tree with this patch and there was a good number
of people using the symlink rather than the preferred name. That part will be
merged later, I think.

Since now we have evidence of less and less users using devfs, we think that
it will not cause too much problems.
