vfio/type1: fix vaddr_get_pfns() return in vfio_pin_page_external()
vaddr_get_pfns() now returns the positive number of pfns successfully
gotten instead of zero. vfio_pin_page_external() might return 1 to
vfio_iommu_type1_pin_pages(), which will treat it as an error, if
vaddr_get_pfns() is successful but vfio_pin_page_external() doesn't
reach vfio_lock_acct().
Fix it up in vfio_pin_page_external(). Found by inspection.
