This fixes a couple of bugs in the buffer handling in virtio-i2c which can
result in incorrect data on the I2C bus or memory corruption in the guest.

I tested this on UML (virtio-uml needs a bug fix too, I will sent that out
later) with the device implementation in rust-vmm/vhost-device.

Vincent Whitchurch (2):
  i2c: virtio: disable timeout handling
  i2c: virtio: fix completion handling
