s4:rpc_server/lsa: pass the correct variable to setInfoTrustedDomain_base()

This requires 'struct lsa_policy_state', we now pass this directly
instead of a instead of an opaque 'struct dcesrv_handle'.

dcesrv_lsa_SetInformationTrustedDomain() passes in a 'struct dcesrv_handle'
with 'struct lsa_trusted_domain_state' before, which results in segfaults.
