In the current code, EV_CODE_EXTRACT macro is used to extract the "sample" field, which then needs to be further processed to fetch rand_samp_elig and rand_samp_mode bits. But the current code is not passing valid sample field to EV_CODE_EXTRACT macro. Patch addresses this by fixing the input for EV_CODE_EXTRACT.
