From the NetLink perspective it looked like a function that: a) allocates new hdr, b) can fail. Neither was true. Let the function return a error code instead of returning the same hdr it was passed to. In case if future Linux NetLink compatibility support calls for reallocating header, pass hdr as pointer to pointer. With KPI that returns a error, propagate domain conversion errors all the way up to NetLink module. This fixes panic when unknown domain is converted to 0xff and this invalid value is passed into NetLink processing.
