MFC r244503 and r246565:
Make sure all USB drivers allocate buffer memory through the USB API and/or busdma.
The following assumptions have been made: umass - buffers passed from CAM/SCSI layer are OK network - mbufs are OK.
Some other nits while at it.

Overhaul monitor mode handling: o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO and remove explicit bpf support from wireless drivers; drivers now use ieee80211_radiotap_attach to setup shared data structures that hold the radiotap header for each packet tx/rx o remove rx timestamp from the rx path; it was used only by the tdma support for debugging and was mostly useless due to it being 32-bits and mostly unavailable o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and per-com state when there are active taps o track the number of monitor mode vaps o use bpf tap and monitor mode vap state to decide when to collect radiotap state and dispatch frames; drivers no longer explicitly directly check bpf state or use bpf calls to tap frames o handle radiotap state updates on channel change in net80211; drivers should not do this (unless they bypass net80211 which is almost always a mistake) o update various drivers to be more consistent/correct in handling radiotap o update ral to include TSF in radiotap'd frames o add promisc mode callback to wi

Create a taskqueue for each wireless interface which provides a serialised sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer.
This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone.
The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.
