The previous autoreplace code assumed that if you were using autoreplace, then
you also had the enclosure SES driver loaded. This could lead to autoreplace
not working if the SES driver wasn't loaded, or if it wasn't creating the
proper enclosure_device symlinks (which has happened). This patch removes
that assumption.
