spi/dw_spi: remove conditional from 'poll_transfer'.
The 'poll_transfer' function employs a conditional to test whether the transmit buffer is valid; in doing so, on a receive operation no data is clocked out, thus no data is clocked in and ultimately errors appear. This removes the conditional as the transmit function will be set to a null writer when the transmit buffer is invalid, allowing the driver to clock 0x00 out to the device to receive data from the device.
