    arp: fixed -Wuninitialized compiler warning · 5990baaa

    Commit 7d472a59 ("arp: always override
    existing neigh entries with gratuitous ARP") introduced a compiler
    warning:
    
    net/ipv4/arp.c:880:35: warning: 'addr_type' may be used uninitialized in
    this function [-Wmaybe-uninitialized]
    
    While the code logic seems to be correct and doesn't allow the variable
    to be used uninitialized, and the warning is not consistently
    reproducible, it's still worth fixing it for other people not to waste
    time looking at the warning in case it pops up in the build environment.
    Yes, compiler is probably at fault, but we will need to accommodate.
