RISC-V: Remove __init on unaligned_emulation_finish()

This function shouldn't be __init, since it's called during hotplug. The
warning says it well enough:

WARNING: modpost: vmlinux: section mismatch in reference:
check_unaligned_access_all_cpus+0x13a (section: .text) ->
unaligned_emulation_finish (section: .init.text)
