spi: Fix WARN when removing spi-fsl-spi module
If CPM mode is not used, the fsl_dummy_rx variable is never allocated. When the cleanup attempts to free it, the reference count is zero and a WARN is generated. The same CPM mode check used in the initialize is applied to the free as well. Tested on 2.6.33 with the previous spi_mpc8xxx driver. The renamed spi-fsl-spi driver looks to have the same problem.
