Can you check if the irq_type value is `SPI0_TWI0_IRQn = 3, at the time of this call. If it is so, then this is some softdevice bug in that version. I see that in latest SDK they have removed the sd_call and called direct NVIC_ functions.

Quick fix would be to replace all sd_nvic functions with NVIC_ functions directly.

APP_ERROR_CHECK(sd_nvic_ClearPendingIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_ClearPendingIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_SetPriority(p_spi_instance->irq_type, p_spi_master_config->SPI_PriorityIRQ));

etc

NVIC_ClearPendingIRQ(p_spi_instance->irq_type);
NVIC_DisableIRQ(p_spi_instance->irq_type);
NVIC_ClearPendingIRQ(p_spi_instance->irq_type);
NVIC_SetPriority(p_spi_instance->irq_type, p_spi_master_config->SPI_PriorityIRQ);

etc
