trafgen: proto: Fix bad field masking
Current logic does OR of existing field value & shift-masked specified value, which is not enough as 0s bits from the specified value will be not set (be cause of OR), so fixed it by reseting original field value by AND with reverted field mask, in otherwords - bits part of original field value is reset to 0s and only after OR-ed with specified shift-masked value.
