i2c: Do not attempt bus clear on split xfer failurestabilize-11101.B
If a split transaction fails after its first half, the chip driver has a
few options for dealing with the bus state. It can either release the
bus by sending a stop bit, or it can leave the bus busy and use a
repeated start for the next transaction. ChromeEC does not support
multimaster I2C, so either condition is acceptable.
TEST=boot a bip with a battery disconnected. Observe that the bus reset
error path is not taken when attempting to read the battery
identification registers.
