[PATCH] uml: fix wall_to_monotonic initialization

Browse Source 
From: Jeff Dike <jdike@addtoit.com>

Initialize wall_to_monotonic correctly.  This fixes a problem where sleeps
lasted about one secone less than they should.  This also called for a bit of
code restructuring, following a patch which Blaisorblade had been keeping.
