i2c: imx: fix i2c issue when reading multiple messages

When reading multiple messages, meaning a repeated start is required,
polling the bus busy bit must be avoided. This must only be done for
the last message. Otherwise, the driver will timeout.

Here an example of such a sequence that fails with an error:
i2ctransfer -y -a 0 w1@0x00 0x02 r1 w1@0x00 0x02 r1
Error: Sending messages failed: Connection timed out
