KVM: x86: Remove 'return void' expression for 'void function'

The requested info will be stored in 'guest_xsave->region' referenced by
the incoming pointer "struct kvm_xsave *guest_xsave", thus there is no need
to explicitly use return void expression for a void function "static void
kvm_vcpu_ioctl_x86_get_xsave(...)". The issue is caught with [-Wpedantic].

Fixes: 2d287ec65e79 ("x86/fpu: Allow caller to constrain xfeatures when copying to uabi buffer")
