Now that KVM prevents setting host-reserved CR4 bits, drop the dedicated XSAVE check in guest_cpuid_has() in favor of open coding similar checks in the SVM/VMX XSAVES enabling flows. Note, checking boot_cpu_has(X86_FEATURE_XSAVE) in the XSAVES flows is technically redundant with respect to the CR4 reserved bit checks, e.g. XSAVES #UDs if CR4.OSXSAVE=0 and arch.xsaves_enabled is consumed if and only if CR4.OXSAVE=1 in guest. Keep (add?) the explicit boot_cpu_has() checks to help document KVM's usage of arch.xsaves_enabled. No functional change intended.
