hugetlb_sysctl_init() is only invoked once by an __init function and is merely a wrapper around another __init function so there is not reason to keep it.
Fixes the following warning when toning down some GCC inline options:
WARNING: modpost: vmlinux: section mismatch in reference: hugetlb_sysctl_init+0x1b (section: .text) -> __register_sysctl_init (section: .init.text)
