powerpc/83xx/mpc832x_rdb: call platform_device_put() in error case in of_fsl_spi_probe()

[ Upstream commit 4d0eea415216fe3791da2f65eb41399e70c7bedf ]

If platform_device_add() is not called or failed, it can not call
platform_device_del() to clean up memory, it should call
platform_device_put() in error case.
