mac80211_hwsim: call ieee80211_tx_prepare_skb under RCU protection
[ Upstream commit 9e2db50f1ef2238fc2f71c5de1c0418b7a5b0ea2 ]
This is needed since it might use (and pass out) pointers to
e.g. keys protected by RCU. Can't really happen here as the
frames aren't encrypted, but we need to still adhere to the
rules.
