Use syscall_helper_register() to register syscalls and do it through the module interface rather than sysinit.

Summary

This pattern is more common and easier to understand.

Looks ok to me, although, since I know nothing about the interface,
I've taken myself off the review.

I think you should actually do the nlm_uninit in MOD_UNLOAD case (modules get MOD_UNLOAD invoked if MOD_LOAD fails). It's fine to have that still fallthrough though.

• Let MOD_UNLOAD handle the failure case.
