i2c: i801: use i2c_mark_adapter_suspended/resumed
When entering the suspend callback, at first we should ensure that
transfers are finished and I2C core can't start further transfers.
Use i2c_mark_adapter_suspended() for this purpose, and complement it
with a call to i2c_mark_adapter_resumed() in the resume path.
