KVM: selftests: Move XSAVE and OSXSAVE CPUID checks into AMX's init_regs()

Browse source

Move the checks on XSAVE and OSXSAVE into init_regs() so that the XSAVE
check is done before setting CR4.OSXSAVE, i.e. before a potential #GP, and
so that the OSXSAVE check is performend immediately after enabling XSAVE
in CR4.
