x86/tdx: Fix RETs in TDX asm 

Because build-testing is over-rated, fix a few trivial objtool complaints:

  vmlinux.o: warning: objtool: __tdx_module_call+0x3e: missing int3 after ret
  vmlinux.o: warning: objtool: __tdx_hypercall+0x6e: missing int3 after ret

Fixes: eb94f1b6a7 ("x86/tdx: Add __tdx_module_call() and __tdx_hypercall() helper functions")
