[patch 8/9] uml - hostfs : unuse ROOT_DEV

[blaisorblade@yahoo.it]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
CC: Christoph Hellwig <hch@infradead.org>

Minimal patch removing uses of ROOT_DEV; next patch unexports it. I've opposed
this, but I've planned to reintroduce the functionality without using
ROOT_DEV.
