iwlwifi: queue: bail out on invalid freeing
...
If we find an entry without an SKB, we currently continue, but
that will just result in an infinite loop since we won't increment
the read pointer, and will try the same thing over and over again.
Fix this.

iwlwifi: queue: don't crash if txq->entries is NULL
...
The code was really awkward, we would first dereference
txq->entries when calling iwl_txq_genX_tfd_unmap and then
we would check that txq->entries is non-NULL.
Fix that by exiting if txq->entries is NULL.

Currently calling iwl_txq_dyn_free only deletes the queue memory/DMA

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.
