[Clang][SYCL] Fix test after 034d4dcad639 (#36278)
Fix sycl-cconv.cpp test that broke after commit 034d4dcad639
which changed SemaChecking to diagnose invalid non-dependent
calls in dependent contexts.
The commit now checks variadic function calls even in template
definitions, not just during instantiation. This means the printf
call on line 18 now emits an error both during template definition
and during instantiation, requiring 2 expected-error directives.
