x86/entry: Add __init to ia32_emulation_override_cmdline()

[ Upstream commit d55f31e29047f2f987286d55928ae75775111fe7 ]

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.

Fixes: a11e097504ac ("x86: Make IA32_EMULATION boot time configurable")
