Subject: net/smc: fix -Wmissing-prototypes warning when CONFIG_SYSCTL not set
Patch-mainline: v5.18-rc1
Git-commit: d9f50991592513cc7633684cbaff65022cfa6816
References: jsc#PED-612

when CONFIG_SYSCTL not set, smc_sysctl_net_init/exit
need to be static inline to avoid missing-prototypes
if compile with W=1.

Since __net_exit has noinline annotation when CONFIG_NET_NS
not set, it should not be used with static inline.
So remove the __net_init/exit when CONFIG_SYSCTL not set.
