x86/tdx: Annotate a noreturn function
objdump complains:
vmlinux.o: warning: objtool: __tdx_hypercall()+0x74: unreachable instruction
because __tdx_hypercall_failed() won't return but panic the guest.
Annotate that that is ok and desired.
Fixes: eb94f1b6a70a ("x86/tdx: Add __tdx_module_call() and __tdx_hypercall() helper functions")
