nfp: flower: fix 'variable 'flow6' set but not used'
Kernel test robot reported an issue after a recent patch about an unused variable when CONFIG_IPV6 is disabled. Move the variable declaration to be inside the #ifdef, and do a bit more cleanup. There is no need to use a temporary ipv6 bool value, it is just checked once, remove the extra variable and just do the check directly.
