4cf2f5904d iwlwifi: queue: avoid memory leak in reset flow 
In case the device is stopped any usage of hw queues needs to be
reallocated in fw due to fw reset after device stop, so all driver
internal queue should also be freed, and if we don't free the next usage
would leak the old memory and get in recover flows
"iwlwifi 0000:00:03.0: dma_pool_destroy iwlwifi:bc" warning.

Also warn about trying to reuse an internal allocated queue.

13f028b4f7 iwlwifi: tx: move handing sync/async host command to trans 
Handling host commands in a sync way is not directly related to PCIe
transport, and can serve as common logic for any transport, so move
it to trans layer.

0179bfff97 iwlwifi: pcie: make iwl_pcie_txq_update_byte_cnt_tbl bus independent 
To avoid duplicating code we need to call iwl_pcie_txq_update_byte_cnt_tbl
function from non bus independent code so make it bus independent.

After moving out all Tx fields not related to pcie-bus
it's time to move the code to a common place.

We also rename all pcie functions name to txq.
