Dr. David Alan Gilbert 7652511473 vhost: Only align sections for vhost-user
I added hugepage alignment code in c1ece84e7c to deal with
vhost-user + postcopy which needs aligned pages when using userfault.
However, on x86 the lower 2MB of address space tends to be shotgun'd
with small fragments around the 512-640k range - e.g. video RAM, and
with HyperV synic pages tend to sit around there - again splitting
it up.  The alignment code complains with a 'Section rounded to ...'
error and gives up.

Since vhost-user already filters out devices without an fd
(see vhost-user.c vhost_user_mem_section_filter) it shouldn't be
affected by those overlaps.

Turn the alignment off on vhost-kernel so that it doesn't try
and align, and thus won't hit the rounding issues.
