Revert "Require a minimum SASL security factor of 56"

This reverts commit 3509545897.

We cannot force increase in minimum SASL security factor until our
consumers are ready to deal with it. Unfortunately, realmd uses
anonymous connection for discovery and validation of IPA LDAP server.

The way it is done is fragile (it doesn't take into account an
advertised IPA version, only checks that 'IPA' string exists in the info
field) but since bumping of minimum SSF prevents reading IPA info field
using anonymous connection, client enrollment fails.

We should get back to bumping minimum SSF after realmd and other
potential consumers are fixed.
