Subject: [PATCH RESEND v3] checkpatch: Fix checks for Kconfig help text

If one patch has Kconfig section, the check script variable '$is_start'
will be set by first 'config' line and the variable '$is_end' is to be
set by the second 'config' line. But patches often has only one
'config' line so we have no chance to set '$is_end', as result below
condition is invalid and it skips check for Kconfig description:

	if ($is_start && $is_end && $length < $min_conf_desc_length) {
		......
	}

When script runs to this condition sentence it means the Kconfig
section parsing has been completed, whatever '$is_end' is true
or not. So removes '$is_end' from condition sentence.
