Lockdep warning will be trigged while rfcomm connection closing.

The locks taken in rfcomm_dev_add:
rfcomm_dev_lock --> d->lock

In __rfcomm_dlc_close:
d->lock --> rfcomm_dev_lock (in rfcomm_dev_state_change)

There's two way to fix it, one is in rfcomm_dev_add we first locking
d->lock then the rfcomm_dev_lock

The other (in this patch), remove the locking of d->lock for
rfcomm_dev_state_change because just locking "d->state = BT_CLOSED;"
is enough.

'rfcomm connect' will trigger lockdep warnings which is caused by
locking diffrent kinds of bluetooth sockets at the same time.

So using sub-classes per AF_BLUETOOTH sub-type for lockdep.

When STA structure insertion fails, it has been allocated but isn't

Implement triggers inside rt2x00 itself based

of using the mac80211 trigger events which do
not work for USB drivers due to the scheduling

The TO_DS filter does not only depend on the FIF_PROMISC_IN_BSS flag
provided by mac80211, but also on the intf_ap_count count.
This makes sense, since when Master mode is active, we should all frames
that are send to the active AP (the device itself).

This means that when an interface is added we should force the
packet filter to be updated during the next mac80211 call of
configure_filter() to make sure the intf_ap_count field is checked.
