Log message:
In iwm(4) avoid locking the NIC redundantly and perform accounting of
locking and unlocking. Make sure we don't unlock 7000 family NICs while
a command is being processed (later NICs apparently don't need this).
Inspired by similar approaches in Linux and Dragonfly, and a patch given
to me by Imre Vadasz.
Tested by me on 7265 and 8260 devices, and on a 7260 device by Stefan Wollny.
