Daniel Jordan 4ab4fcfce5 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.

Fixes: be16c1fd99 ("vfio/type1: Change success value of vaddr_get_pfn()")
