[PATCH] mac80211: don't call conf_tx under RCU lock

[Johannes Berg <johannes@sipsolutions.net>]

Reinette pointed out that with the sta_info RCU-ification
the behaviour here changed and the conf_tx callback is
now invoked under RCU read lock. That is not necessary so
this patch restores the original behaviour
