x86/split_lock: Don't warn about unknown split_lock_detect parameter
The split_lock_detect command line parameter is handled in sld_setup() shortly
after cpu_parse_early_param() but still before parse_early_param().
Add a dummy parsing function so that parse_early_param() doesn't later
complain about the "unknown" parameter split_lock_detect=, and pass it along
to init.
