fix: add missing variadic macro argument in Tensor::sync

REQUIRES_OK(expr, ...) is a variadic macro defined in macros.h.
C++14 requires at least one argument be passed for the ... parameter;
omitting it is a C++20 extension that triggers -Wvariadic-macro-arguments-omitted
under icpx -pedantic.

Tensor::sync was the only call site in the whole codebase that omitted the
second argument. Add a descriptive error message to keep the macro usage
consistent with every other REQUIRES_OK call.
