Revert "config: Always use osd_memory_target if set" 

This reverts commit 4d1fdd2b05.

This breaks the backward compatibility with previous osd_memory_target
calculation and we could have a value lower than the minimum value allowed
(896M) which causes some ceph commands to fail (like ceph assimilate-conf).
