[PATCH v3 3/4] iw: use get_cf1 and struct chanmode for ocb

[Sven Eckelmann <sven@open-mesh.com>]

The struct chanmode and the function get_cf1 is already used by ibss and
mesh. Also use it for ocb to make it consistent for for all join functions.

v3:
 * split patch into two different patches (0001/0002) as request by
   Julian Calaby <julian.calaby@gmail.com>
 * change join_ocb to also use get_cf1
 * move NOHT to the last entry in the mesh/ibss join usage texts as
   requested by Julian Calaby <julian.calaby@gmail.com>
v2:
 * rebase from v4.3-ish version to current master
