skb_tx_timestamp() is used for tx software timestamp enabled by SOF_TIMESTAMPING_TX_SOFTWARE while SKBTX_HW_TSTAMP is used for SOF_TIMESTAMPING_TX_HARDWARE. As it clearly shows they are different timestamps in two dimensions, it's not appropriate to group these two together in the if-statement. This patch completes three things: 1. make the software one standalone. Users are able to set both timestamps together with SOF_TIMESTAMPING_OPT_TX_SWHW flag. 2. make the software one generated after the hardware timestamp logic to avoid generating sw and hw timestamps at one time without SOF_TIMESTAMPING_OPT_TX_SWHW being set. 3. move the software timestamp call as close to the door bell.
