       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
