net: ignore sysctl_devconf_inherit_init_net without SYSCTL
When CONFIG_SYSCTL is turned off, we get a link failure for
the newly introduced tuning knob.
net/ipv6/addrconf.o: In function `addrconf_init_net':
addrconf.c:(.text+0x31dc): undefined reference to `sysctl_devconf_inherit_init_net'
Add an IS_ENABLED() check to fall back to the default behavior
(sysctl_devconf_inherit_init_net=0) here.
Fixes: 856c395cfa63 ("net: introduce a knob to control whether to inherit devconf config")
