    staging: rtl8723au: Eliminate struct HT_info_element

    Yet another duplicate version of struct ieee80211_ht_operation

    Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com>

introduced a bad error, applying the wrong value as the mask when
determining the location of the 40MHz channel, effectively making it
always determining it as not present. This caused hangs and delays
when running in 40MHz channel mode.

This should get it right.
