wifi: mac80211: Use flexible array in struct ieee80211_tim_ie
Currently struct ieee80211_tim_ie defines:
u8 virtual_map[1];
Per the guidance in [1] change this to be a flexible array.
Per the discussion in [2] wrap the virtual_map in a union with a u8
item in order to preserve the existing expectation that the
virtual_map must contain at least one octet (at least when used in a
non-S1G PPDU). This means that no driver changes are required.
