migration: mmap error check fix
mmap man page: "On success, mmap() returns a pointer to the mapped area. On error, the value MAP_FAILED (that is, (void *) -1) is returned, and errno is set to indicate the cause of the error." The check in postcopy_get_tmp_page is definitely wrong and should be fixed. Signed-off-by: Evgeny Yakovlev <eyakovlev@virtuozzo.com> Signed-off-by: Denis V.
