In commit 2e92e6f2c50b4baf85cca968f0e6f1b5c0df7d39 ("mac80211: use rate
index in TX control") I forgot to initialise a few new variables to -1 which
means that the rate control algorithm is never triggered and 0 is used as
the only rate index, effectively fixing the transmit bitrate at the lowest
supported.

This patch adds the missing initialisation.
