x86/mce: Fix monarch timeout setting through the mce= cmdline option

Using "mce=1,10000000" on the kernel cmdline to change the
monarch timeout does not work. The cause is that get_option()
does parse a subsequent comma in the option string and signals
that with a return value. So we don't need to check for a second
comma ourselves.
