Liwei Song 3abc229cfc i2c: ismt: fix wrong device address when unmap the data buffer 
commit 17e83549e199d89aace7788a9f11c108671eecf5 upstream.

Fix the following kernel bug:

This happen When run "i2cdetect -y 0" detect SMBus iSMT adapter.

After finished I2C block read/write, when unmap the data buffer,
a wrong device address was pass to dma_unmap_single().

To fix this, give dma_unmap_single() the "dev" parameter, just like
what dma_map_single() does, then unmap can find the right devices.
