Subject: rt2x00: fix a crash bug in the HT descriptor handling fix
From: Felix Fietkau <nbd@xxxxxxxxxxx>
commit b4089d6d8e71a7293e2192025dfa507a04f661c4 upstream.
Commit "rt2x00: fix HT TX descriptor settings regression"
assumes that the control parameter to rt2x00mac_tx is always non-NULL.
There is an internal call in rt2x00lib_bc_buffer_iter where NULL is
passed. Fix the resulting crash by adding an initialized dummy on-stack
ieee80211_tx_control struct.
