[CRIU] [PATCH] restore: Use in_vma_area helper in restore_priv_vma_content

[Cyrill Gorcunov]

Because a sequence of VMAs is not obligated to not have
holes inbetween, plain vma.end check is not enough, use
in_vma_area instead to make sure that page addres we're
using to restore page contents do belong to particular
vma.
