rt2x00: Remove obsolete rt2x00queue_align_payload
Since commit d1c3a37ceeb1a5ea02991a0476355f1a1d3b3e83 ("mac80211: clarify alignment docs, fix up alignment") removed the requirement for a 4-byte aligned payload rt2x00queue_align_payload is obsolete as mac80211 will align the payload when it passes the frame to the net stack. As a result we can remove the call to rt2x00queue_align_payload in the rx path and since that's the last user we can remove rt2x00queue_align_payload altogether. One advantage is that we save some alignment operations for frames that don't need to be aligned (for example beause they are not passed to the net stack).
