This uses a static lbs_cmd_async_callback function, which is a
noop. Just setting the callback argument to __lbs_cmd_async()
to NULL won't work, because then the cmdnode wouldn't be
released.
This also makes __lbs_cmd_async() a static method, which is
now only used by lbs_cmd() and lbs_cmd_async().

The struct enc_key probably wants to die too, but that can come later.

sizeof(*cmd) is going to give the total size of the data structure that
we allocated, more often than not. But the size of the command to be
_sent_ could be a lot smaller, as it is in the KEY_MATERIAL and
SUBSCRIBE_EVENT commands for example. So swap them round; let the caller
set the _command_ size explicitly in the header, and infer the
maximum response size from the data structure.

There is weirdness here; the firmware seems to refuse to change channels
at will.

Also, check that suspend is refused if HOST_SLEEP_CFG hasn't been done.

We (ab)use priv->fw_ready to stop the worker thread from sending more
commands or data after the response to the HOST_SLEEP_ACTIVATE command
comes in. And we set it from the callback function _directly_ to ensure
that the worker thread sees it immediately; if we did it in
lbs_suspend() after waking up, that might be too late.

This way, it looks more like a normal function.

If stupid people like me give it arguments with the wrong type (like a
pointer to the structure, for example, instead of the structure itself),
then we should probably notice that at compile time. Otherwise, much
confusion ensues.

A simple callback which copies the response back into the
command buffer that was used to send the command to the
card. Will allow for direct command processing outside
the mega-switches in cmd.c and cmdresp.c.

Move direct command handling through __lbs_cmd() over to using the
header as the first member of the command structure, and only define
the __lbs_cmd() callback in one place rather than 3. Convert boot2
version command to new usage.

Define a macro that relieves the caller from having to use sizeof on
the command structure when calling lbs_cmd(), and move the prototype
of __lbs_cmd() to a new cmd.h file.
