    ve/net: Fix possible fall through when cheking capability for ETHTOOL_SEEPROM
    
    This does not change the logic and capable() supersedes ns_capable(),
    but the additional "break" makes the compiler happy.
    
    Fixes: 53c8b1085e51 ("ve/net: restrict ethtool to CT root userns and
    prohibit EEPROM change")
