x86/entry/32: Pull the MSR_IA32_SYSENTER_CS update code out of native_load_sp0()
This causes the MSR_IA32_SYSENTER_CS write to move out of the paravirt callback. This shouldn't affect Xen PV: Xen already ignores MSR_IA32_SYSENTER_ESP writes. In any event, Xen doesn't support vm86() in a useful way. Note to any potential backporters: This patch won't break lguest, as lguest didn't have any SYSENTER support at all.
