wifi: cfg80211: adjust allocation of colocated AP data

Browse Source 
[ Upstream commit 1a0d24775cdee2b8dc14bfa4f4418c930ab1ac57 ]

In 'cfg80211_scan_6ghz()', an instances of 'struct cfg80211_colocated_ap'
are allocated as if they would have 'ssid' as trailing VLA member. Since
this is not so, extra IEEE80211_MAX_SSID_LEN bytes are not needed.
Briefly tested with KUnit.
