Subject: [PATCH v2 0/2] wifi: Fix struct ieee80211_tim_ie::virtual_map

To align with [1] change struct ieee80211_tim_ie::virtual_map to be a
flexible array and fix all size references to account for the change
in struct size.

As a precursor, add a size check in a place where one is currently
missing.
