KVM: VMX: Always inline eVMCS read/write helpers

Browse source

Tag all evmcs_{read,write}() helpers __always_inline so that they can be
freely used in noinstr sections, e.g. to get the VM-Exit reason in
vcpu_vmx_enter_exit() (in a future patch).  For consistency and to avoid
more spot fixes in the future, e.g. see commit 010050a863 ("x86/kvm:
Always inline evmcs_write64()"), tag all accessors even though
evmcs_read32() is the only anticipated use case in the near future.  In
practice, non-KASAN builds are all but guaranteed to inline the helpers
anyways.

  vmlinux.o: warning: objtool: vmx_vcpu_enter_exit+0x107: call to evmcs_read32()
                               leaves .noinstr.text section
