    net80211: improve error handling from ieee80211_parse_beacon()
    
    Following up on fb8c87b4f3bfdfac014f9d894fe75fbad0391b24, which was
    supposed to go into all supported branches, increase ieee80211_scanparams
    status field from 8bit to 32bit (enum size) and add a dedicated error
    code for Mesh ID.

    (cherry picked from commit 7354782698f1cf5d6b368a9b1e65cfe3ee7f235c)
