[SYCL] Check return of Expected<T> when reading section size content

Community pull down introduced Expected<T> on the return of getContents.  Apply
the needed check after return to satisfy.

From the llvm manual: All Error instances, whether success or failure, must be
either checked or moved from (via std::move or a return) before they are
destructed
