Stub out the enable_evmcs static key for CONFIG_HYPERV=n. gcc (as of gcc-12) isn't clever enough to elide the nop placeholder when there's no code guarded by a static branch. With gcc-12, because of the vast number of VMCS accesses, eliminating the nops reduces the size of kvm-intel.ko by ~7.5% (200KiB). Patch 1 is tangentially related cleanup. Applies on `git@xxxxxxxxxx:kvm-x86/linux.git vmx`.
