ipvs: Wrap sysctl_cache_bypass and remove ifdefs in ip_vs_leave
With sysctl_cache_bypass now a compile time constant the compiler can
figue out that it can elimiate all of the code that depends on
sysctl_cache_bypass being true.
Also remove the duplicate computation of net previously necessitated
by #ifdef CONFIG_SYSCTL
