xen/balloon: fix accounting in alloc_xenballooned_pages error path
commit 1951fa33ec259abdf3497bfee7b63e7ddbb1a394 upstream.
target_unpopulated is incremented with nr_pages at the start of the
function, but the call to free_xenballooned_pages will only subtract
pgno number of pages, and thus the rest need to be subtracted before
returning or else accounting will be skewed.
