P Praneesh fixed this:
b290b591dbdd ath12k: remove magic number offset in rx_user_status struct

Yeah, in general that would be good. But in this case it would also help
if struct hal_rx_user_status word0 and word1 fields would be renamed to
better reflect what they actually are:
u32 ul_ofdma_user_v0_word0;
u32 ul_ofdma_user_v0_word1;
