[PATCH 3/7] spi: dw: fix warning unused variable 'ret'

[Ike Panhc]

From: Anders Roxell <anders.roxell at linaro.org>

BugLink: https://bugs.launchpad.net/bugs/1826142

When CONFIG_SPI_DESIGNWARE are enabled we see the unused variable
warning in dw_spi_setup.

../drivers/spi/spi-dw.c: In function ‘dw_spi_setup’:
../drivers/spi/spi-dw.c:400:6: warning: unused variable ‘ret’ [-Wunused-variable]
  int ret;
      ^~~

Remove the unused varable.
