Antti Palosaari 4c7cad4bbf [media] rtl28xxu: retry failed i2c messages 
Sometimes i2c transfer fails. That happens especially when large
amount of data is written sequentially eg. firmware download.
Problem arises with both integrated rtl2832 demod and external
mn88472 demod, which is clear indicator it is busy i2c bus issue.
Use i2c core retry logic in order fix the issue by repeating failed
message. Another solution which also works is to add ~100us delay
between i2c messages - but repeating sounds more elegant and does
not cause any extra delay for success cases.
