cephadm: remove restriction for crush device classes

A restriction has been introduced here (https://github.com/ceph/ceph/commit/6c6cb2f5130dbcf8e42cf03666173948411fc92b) which doesn't let OSDs be created with custom crush device classes.
Crush Device Class is the key that helps the crush distinguish between multiple storage classes, so it must accept any custom names.
