spi: dw: fix kernel crash due to NULL pointer dereference

The obvious fix after the commit d9c73bb8a3a5 "spi: dw: add support for gpio
controlled chip select". This patch fixes the issue by using locally defined
temporary variable.

Fixes: d9c73bb8a3a5 (spi: dw: add support for gpio controlled chip select)
