@brief Queue a SPI transaction for interrupt transaction execution. Get the result by spi_device_get_trans_result.

@note Normally a device cannot start (queue) polling and interrupt transactions simultaneously.

@param handle Device handle obtained using spi_host_add_dev @param trans_desc Description of transaction to execute @param ticks_to_wait Ticks to wait until there’s room in the queue; use portMAX_DELAY to never time out. @return - ESP_ERR_INVALID_ARG if parameter is invalid. This can happen if SPI_TRANS_CS_KEEP_ACTIVE flag is specified while the bus was not acquired (spi_device_acquire_bus() should be called first) or set flag SPI_TRANS_DMA_BUFFER_ALIGN_MANUAL but tx or rx buffer not DMA-capable, or addr&len not align to cache line size - ESP_ERR_TIMEOUT if there was no room in the queue before ticks_to_wait expired - ESP_ERR_NO_MEM if allocating DMA-capable temporary buffer failed - ESP_ERR_INVALID_STATE if previous transactions are not finished - ESP_OK on success
