Du Cheng ed13df88c6 cfg80211: remove WARN_ON() in cfg80211_sme_connect 
commit 1b5ab825d9acc0f27d2f25c6252f3526832a9626 upstream.

A WARN_ON(wdev->conn) would trigger in cfg80211_sme_connect(), if multiple
send_msg(NL80211_CMD_CONNECT) system calls are made from the userland, which
should be anticipated and handled by the wireless driver. Remove this WARN_ON()
to prevent kernel panic if kernel is configured to "panic_on_warn".

Bug reported by syzbot.
