Instead of setting the tx_cmd length in the mvm code, which is complicated by the fact that DQA may want to temporarily store the SKB on the side, adjust the length in the PCIe code which also knows about this since it's responsible for duplicating all those headers that are account for in this code.
As the PCIe code already relies on the tx_cmd->len field, this doesn't really introduce any new dependencies.
To make this possible we need to move the memcpy() of the TX command until after it was updated.
This does even simplify the code though, since the PCIe code already does a lot of manipulations to build A-MSDUs correctly and changing the length becomes a simple operation to see how much was added/removed, rather than predicting it.
