validate: drop a check
validate: drop a check

Since the ISO install method removal, ceph-ansible isn't able
to detect wheter the user is deploying in a 'disconnected environment'.
By the way, given that ceph-ansible is available only for upgrading to RHCS 5,
this check doesn't make sense anymore, let's drop it.
