Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/kpc2000/kpc_spi/spi_driver.c: In function
âkp_spi_transfer_one_messageâ:
drivers/staging/kpc2000/kpc_spi/spi_driver.c:282:9: warning: variable
âstatusâ set but not used [-Wunused-but-set-variable]
int status = 0;
^~~~~~
The variable 'status' is not used any more, remve it.
