Fix a regression from VLAN assignment using WPA/WPA2 passphrase/PSK

Browse source 
This extension of VLAN assignment code had a bug in one of the code
paths where vlan_id could have been left uninitialized. This could
result in SAE authentication getting rejected in cases where VLAN
assignment is not used if the uninitialized stack memory had nonzero
value.

Fixes: dbfa691df4 ("VLAN assignment based on used WPA/WPA2 passphrase/PSK")
