spi: dw: remove useless dws->transfer_handler check
transfer_handler is initialized before any DW SPI interrupt is
unmasked. While the IRQ is registered but the handler is NULL,
dw_spi_hw_init() has all DW SPI interrupts disabled. Therefore
dw_spi_irq() cannot observe a DW SPI interrupt with a NULL
transfer_handler.
