wifi: mac80211: supplement parsing of puncturing bitmap

Browse Source 
Current mac80211 won't parsing puncturing bitmap when process EHT
Operation element in 6 GHz band or Bandwidth Indication element. This
leads to puncturing bitmap cannot be updated in related situations, such
as connecting to an EHT AP in 6 GHz band.

So supplement parsing of puncturing bitmap for these elements.
