Revert "osd: generate device list for osd_auto_discovery on rolling_update"

This reverts commit e84f11e99e.

This commit was giving a new failure later during the rolling_update
process. Basically, this was modifying the list of devices and started
impacting the ceph-osd itself. The modification to accomodate the
osd_auto_discovery parameter should happen outside of the ceph-osd.

Also we are trying to not play ceph-osd role during the rolling_update
process so we can speed up the upgrade.
