wifi: ath12k: fix desc address calculation in wbm tx completion
In tx completion, status desc is obtained from offsetting the address
from wbm ring. Having HTT_TX_WBM_COMP_STATUS_OFFSET(8) and reserved 8
bytes in status desc offsets the address twice and read the values
from the incorrect address. Hence, remove the
HTT_TX_WBM_COMP_STATUS_OFFSET from wbm completion address calculation.
Also this patch is applicable for WCN7850.
