mac80211: allow non-standard VHT MCS-10/11
Some AP can possibly try non-standard VHT rate and mac80211 warns and drops
packets, and leads low TCP throughput.
Rate marked as a VHT rate but data is invalid: MCS: 10, NSS: 2
WARNING: CPU: 1 PID: 7817 at net/mac80211/rx.c:4856 ieee80211_rx_list+0x223/0x2f0 [mac8021
Since commit c27aa56a72b8 ("cfg80211: add VHT rate entries for MCS-10 and MCS-11")
has added, mac80211 adds this support as well.
After this patch, throughput is good and iw can get the bitrate:
rx bitrate: 975.1 MBit/s VHT-MCS 10 80MHz short GI VHT-NSS 2
or
rx bitrate: 1083.3 MBit/s VHT-MCS 11 80MHz short GI VHT-NSS 2
