    wifi: always retry ioctl for ifindex
    
    ifindex() caches the result of ioctl(SIOCGIFINDEX) and never
    retries it, since the interface name strcmp succeeds after the
    first call. if the interface does not exist when slstatus starts
    (e.g. iwd with default config destroys/recreates interfaces
    depending on service state), the ioctl fails and the stale
    result is returned on all subsequent calls.
    
    based on a patch by ryhpez, with input from Taha Medhous
