Subject: [PATCH 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.

[1] https://docs.kernel.org/process/deprecated.html#zero-length-and-one-element-arrays

Internal note: posting to kernel@...cinc.com since although I believe
the legacy Qualcomm Atheros exception applies, it doesn't hurt to get
feedback/green light from the core kernel team before posting
upstream.
