The vmbus driver cannot be unloaded; the windows host does not
permit this: A) All guest resources given to the host cannot
be recovered and B) Windows host does not permit reloading the
vmbus_driver without re-booting the guest. Both these issues
are host related. Acknowledge this reality and cleanup the
vmbus driver accordingly. Note that, ideally we will want to handle

unloading the vmbus driver will not be possible because of the

Code cleanup. Make code more readable by converting different macro's
(WL_TRACE, WL_AMPDU, etc) into one BCMMSG. This single macro uses wiphy_err()
instead of printk(), so the user is able to correlate a log
message to our driver. This patch only replaces WL_TRACE, subsequent patches

wlan driver does a reconnection on its own and after connection
is re-established, reports it as ROAM_EVENT to cfg. Now this event
is handled as work queue. It could very well happen that by the
time this event gets handled, cfg would have aged out the bss and
we get the following WARN_ON in __cfg80211_roamed function in file
