Fix __curhs_set_key ignores the return from __wt_buf_set

Summary

The use of WT_IGNORE_RET ignores the error returned by __wt_buf_set. We should fix this.

    if (arg_count > 1) {

        datastore_key = va_arg(ap, WT_ITEM *);

        WT_IGNORE_RET(__wt_buf_set(

          session, hs_cursor->datastore_key, datastore_key->data, datastore_key->size));

        F_SET(hs_cursor, WT_HS_CUR_KEY_SET);

    } else {
