qcom-geni-se: Avoid dumping of GENI registers in console 



In UART usecase, The file used for transfers can contain 0 bytes of data.
Current logic in serial driver will treat 0 byte data as RX invalid data
and dump GENI registers in console which can results into
watchdog crash.

This change will avoid logging of GENI registers in console.
