dm: spi: Fix spi_free_slave() freed memory write
Remove setting slave->dev to NULL after the device_remove() call.
The slave pointer points to dev->parent_priv, which has already
been freed by device_free(), called from device_remove() in the
preceding line. Writing to slave->dev may cause corruption of the
dlmalloc free chunk forward pointer of the previously freed chunk.
