cli: fix for no-MT mode

when cli is compiled without MT support,
invoking ZSTD_p_nonBlockingMode result in an error code.

This patch only sets ZSTD_p_nonBlockingMode when ZSTD_MULTITHREAD is set, meaning there is MT support.

The error code could also be intentionnally ignored (there is no side effect).
