iw: Use NL80211_FREQUENCY_ATTR_NO_IR channel attribute

iw: Use NL80211_FREQUENCY_ATTR_NO_IR channel attribute

Align iw with the change in nl80211.h where NL80211_FREQUENCY_ATTR_NO_IBSS
and NL80211_FREQUENCY_ATTR_PASSIVE_SCAN were replaced by
NL80211_FREQUENCY_ATTR_NO_IR.

In case both NL80211_FREQUENCY_ATTR_NO_IR and __NL80211_FREQUENCY_ATTR_NO_IBSS
are set, assume that a new kernel is used and use the NO_IR notation,
otherwise use the previous notation.

This change requires nl80211.h with the new definitions
