nl80211: fix channel switch parsing

The nl80211 attribute NL80211_ATTR_CSA_C_OFF_BEACON should be nested
inside NL80211_ATTR_CSA_IES, but commit ee4bc9e75811d2c0cb5f2a2fc5b5
("nl80211: enable IBSS support for channel switch announcements")
added a check in the outer message attributes.

Fix channel switch calls by removing the erroneus condition.
