The Free Software Foundation address is superfluous and causes
checkpatch to issue a warning when present. Remove all paragraphs
with FSF's address to prevent that.

De-inline iwl_trans_ref/unref and move it to common transport code
in preparation for more common code to come to these functions.

When toggling the RF-kill pin quickly in succession, the driver can
get rather confused because it might be in the process of shutting
down, expecting all commands to go through quickly due to rfkill,
but the transport already thinks the device is accessible again,
even though it previously shut it down. This leads to bugs, and I
even observed a kernel panic.
Avoid this by making the PCIe code only report that the radio is
enabled again after the higher layers actually decided to shut it
off.
This also pulls out this common RF-kill checking code into a common
function called by both transport generations and also moves it to
the direct method - in the internal helper we don't really care
about the RF-kill status anymore since we won't report it up until
the stop anyway.

Contrary to what some of the comments say, if rfkill was
asserted the transport will return -ERFKILL instead of
success, if CMD_WANT_SKB was set, so it's not necessary
to check cmd.resp_pkt for being NULL if the return code
was success.
Validate that this is true in iwl_trans_send_cmd().
Most of the other code modifications were done with the
following spatch:
@@
struct iwl_host_cmd cmd;
identifier pkt;
@@
<...
(
pkt = cmd.resp_pkt;
...
-if (!pkt) { ... }
|
pkt = cmd.resp_pkt;
...
-if (WARN_ON(!pkt)) { ... }
|
-if (!cmd.resp_pkt) { ... }
)

Now that we have 512 queues, add a wait for single TX
queue to gen2.
This replaces gen1 wait_tx_queues_empty, which was limited
to 32 queues.

We don't need this parameter anymore, since we always pass 0 anyway.
Remove it from the structure and from all the relevant functions.

New hardware supports bigger TFDs and TBs.
Introduce the new formats and adjust defines and code
relying on old format.
Changing the actual TFD allocation is trickier and
deferred to the next patch.
