Vsyscall emulation has two modes of operation: XONLY and EMULATE. The default XONLY mode is now supported with a LASS-triggered #GP. OTOH, LASS is disabled if someone requests the deprecated EMULATE mode via the vsyscall=emulate command line option. So, remove the restriction on LASS when the overall vsyscall emulation support is compiled in. As a result, there is no need for setup_lass() anymore. LASS is enabled by default through a late_initcall().
