virSCSIHostFindByPCI: Fix link detection
Inside of virSCSIHostFindByPCI() there's a loop which iterates of entries of "/sys/class/scsi_host" directory trying to identify all symlinks (which then point to a SCSI device, but that's not important right now). But the way virFileIsLink() is called can never return a truthful reply - because it's called over dent->d_name instead of full path. Fix this by moving the virFileIsLink() call and passing constructed path into it. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
