Jean Delvare 7a72e3b94f i2c: i801: Fix block process call transactions 
[ Upstream commit c1c9d0f6f7f1dbf29db996bd8e166242843a5f21 ]

According to the Intel datasheets, software must reset the block
buffer index twice for block process call transactions: once before
writing the outgoing data to the buffer, and once again before
reading the incoming data from the buffer.

The driver is currently missing the second reset, causing the wrong
portion of the block buffer to be read.
