[src/phil-wifi]: src/sys/dev/usb Remove configuring 40Mhz channels for now.
details: https://anonhg.NetBSD.org/src/rev/775d4cee37de
branches: phil-wifi

description:
Remove configuring 40Mhz channels for now.
Avoid duplicate state transitions in urtwn_newstate.
Avoid changing channel parameters in urtwn_newstate.
Rework of tx desc parameters for all types of packets.
Don't create a percpuq as the stack is not expecting it //XXX not sure
Tested connections to an open 11n network with 8188CUS, 8192CU and 8192EU
usb adaptors.
