x86/cpu: Remove LASS restriction on vsyscall emulation
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().
