fix(esp-tls): Reduce parameter check for esp_tls_conn_read

Browse Source 
Previously the *data parameters of esp_tls_conn_read
    was required to be non-NULL after espressif/esp-idf!28358.
    This prevents users from using a functionality in esp_tls_conn_read
    where calling `esp_tls_conn_read(ctx, NULL, 0);` triggers the
    transfer of contents from tcp layer to mbedtls (ssl) layer.
    After this the user can read the contents from
    esp_tls_get_bytes_avail().
    This commit removes the additional NULL check on the data field
    to keep this functionality enabled.
