Cursors need to be in the GTT domain when being accessed by the GPU.
Previously this was a fortuitous byproduct of userspace using pwrite()
to upload the image data into the cursor. The redundant clflush was
removed in commit 9b8c4a and so the image was no longer being flushed
out of the caches into main memory. One could also devise a scenario
where the cursor was rendered by the GPU, prior to being attached as the
cursor, resulting in similar corruption due to the missing MI_FLUSH.

* Black screen on G45

The mac80211 changes to idle almost immediately after transmitting some
frames, such as deauth etc. When going to idle, the wl1271 is disconnected,
which causes TX frames already on buffers, but not yet transmitted, to be
deleted.
To make sure deauth frames reach the air, allow the TX buffers to flush
before proceeding to idle.

The wl1271 uses a session counter in CMD_JOIN and TX frame descriptors. This
counter is used to determine which frames to drop when the CMD_JOIN is
executed.
The driver executes CMD_JOIN multiple times upon association and sometimes
disassociation, and we don't want any frames to get lost.
Fix this by incrementing the session counter only when leaving idle (not every
CMD_JOIN as before.) Also, remove the TX flush flag from the CMD_JOIN options.

When sending action frames, we want to verify
that we do that on the correct channel. However,
checking the channel type in addition can get in
the way, since the channel type could change on
the fly during an association, and it's not
useful to have the channel type anyway since it
has no effect on the transmission. Therefore,
make it optional to specify so that if wanted,
it can still be checked, but is not required.

As far as we know, only NF calibration interferes with RX/TX so we can
leave the queues enabled for the other calibrations.
BTW: Stopping the queues is not enough for avoiding transmissions, since there
might be packets in the queue + beacons are also sent regularly! But i leave it
like this until we have a better solution (stopping TX DMA?).
