mac80211: minstrel_ht: do not sample unsupported rates
ATM minstrel_ht does not check whether a sampling rate is supported.
Unsupported rates attempts can trigger when there are holes in bitfields
of supported MCSes belonging to the same group (e.g many devices are
MCS32 capable without MCS33->39 capable, also we systematically have a
hole for CCK rates).
Drop any attempts to sample unsupported rates, as suggested by Felix.
This is not a problem in minstrel which fills a per STA sample table
with only supported rates (though only at init).
