x86/entry: Add __init to ia32_emulation_override_cmdline()

ia32_emulation_override_cmdline() is an early_param() arg and these
are only needed at boot time. In fact, all other early_param() functions
in arch/x86 seem to have '__init' annotation and
ia32_emulation_override_cmdline() is the only exception.
