spi/pl022: Fix device remove function
The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. An extra call to spi_master_put is unnecessary and results in an access to free memory. Drop it.
