carl9170: fix missing bit-wise or operator for tx_params
commit 02a95374b5eebdbd3b6413fd7ddec151d2ea75a1 upstream.
Currently tx_params is being re-assigned with a new value and the
previous setting IEEE80211_HT_MCS_TX_RX_DIFF is being overwritten.
The assignment operator is incorrect, the original intent was to
bit-wise or the value in. Fix this by replacing the = operator
with |= instead.
Kudos to Christian Lamparter for suggesting the correct fix.
