[PATCH] docs: format kernel-parameters -- as code

[Stephen Kitt <steve@sk2.org>]

The current ReStructuredText formatting results in "--", used to
indicate the end of the kernel command-line parameters, appearing as
an en-dash instead of two hyphens; this patch formats them as code,
"``--``", as done elsewhere in the documentation.
