This attribute indicates successful IBSS or AP connection has been
established. However, this no longer works for virtual interfaces.
As it turns out this attribute is identical to the CONNECTED bit
in struct brcmf_cfg80211_vif::sme_state. This patch removes the
attribute and rework some functions relying on it.

Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.
Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

The problem here is that we loop until "remained_buf_len" is less than
zero, but since it is unsigned, it never is.
"remained_buf_len" has to be large enough to hold the value from
"mgmt_ie_buf_len". That variable is type u32, but it only holds small
values so I have changed to both variables to int.
Also I removed the bogus initialization from "mgmt_ie_buf_len" so that
GCC can detect if it is used unitialized. I moved the declaration of
"remained_buf_len" closer to where it is used so it's easier to read.
