ipq806x: i2c: stop transfer as soon as an error is reported
I2c transfer may consist of multiple segments (for instance write
segment to set the register address and then a read segment to read
the register value). Transfer should be stopped as soon as a segment
processing error has been reported.
BRANCH=master
BUG=chrome-os-partner:35328
TEST=transfer shall not process the read segment when the write segment fails
