Subject: [PATCH 5.1 086/115] kvm: vmx: Fix -Wmissing-prototypes warnings

[ Upstream commit 4d259965655c92053f3255aca14d81aab1e21219 ]

We get a warning when build kernel W=1:
arch/x86/kvm/vmx/vmx.c:6365:6: warning: no previous prototype for ‘vmx_update_host_rsp’ [-Wmissing-prototypes]
 void vmx_update_host_rsp(struct vcpu_vmx *vmx, unsigned long host_rsp)

Add the missing declaration to fix this.
