rt2x00: Minor optimization for devices with RTS/CTS offload

Browse Source 
Only devices that don't have RTS/CTS offload need to check for
IEEE80211_TX_RC_USE_RTS_CTS and IEEE80211_TX_RC_USE_CTS_PROTECT.

By swapping both conditions we keep the same number of needed conditionals
for devices without RTS/CTS offload but save one conditional on devices
with RTS/CTS offload.
