xen/balloon: Move dec_totalhigh_pages() from __balloon_append() to balloon_append()
git commit 9be4d4575906af9698de660e477f949a076c87e1 (xen: add
extra pages to balloon) splited balloon_append() into two functions
(balloon_append() and __balloon_append()) and left decrementation
of totalram_pages counter in __balloon_append(). In this situation
if __balloon_append() is called on i386 with highmem page referenced
then totalhigh_pages is decremented, however, it should not. This
patch corrects that issue and moves dec_totalhigh_pages() from
__balloon_append() to balloon_append(). Now totalram_pages and
totalhigh_pages are decremented simultaneously only when
balloon_append() is called.
