Subject: mac80211: Suppress NEW_PEER_CANDIDATE event if no room

From: Masashi Honma <[email protected]>

[ Upstream commit 11197d006bcfabf0173a7820a163fcaac420d10e ]

Previously, kernel sends NEW_PEER_CANDIDATE event to user land even if the found peer does not have any room to accept other peer. This causes continuous connection trials.
