KVM: x86: Add proper ReST tables for userspace MSR exits/flags
Add ReST formatting to the set of userspace MSR exits/flags so that the
resulting HTML docs generate a table instead of malformed gunk. This
also fixes a warning that was introduced by a recent cleanup of the
relevant documentation (yay copy+paste).
