vdev_id: Fix enclosure_symlinks feature
The vdev_id.conf "enclosure_symlinks" option persistently creates
and maps /dev/by-enclosure symlinks to dynamic /dev/sg* devices.

This patch fixes two issues:

1. The enclosure_symlinks feature was accidentally broken in:

   vdev_id: Support daisy-chained JBODs in multipath mode

2. Even when working, the feature numbered the enclosure
   sequentially rather than by HBA port number.  That meant that
   if a port was down or didn't appear in sysfs, then the
   enclosure_sumlinks numbers would be numbered wrong.
