smbd: avoid become_user_without_service() in close_remove_share_mode()

Here we called become_user_without_service() just in order to be able to fetch
the nt_token and unix_token subsequently via
get_current_[nt|u]tok(conn). The same can be achieved by fetching the
session_info with smbXsrv_session_info_lookup().
