[PATCH v2 4/4] checkpatch: kconfig: clarify warning for paragraph length

[Nicolai Fischer]

Currently checkpatch displays a warning if it detects a help text
of a Kconfig option which is too short. However the warning does
not contain any further information.
This adds the expected and currently detected number of lines
to the warning, which makes it more obvious why checkpatch
is warning.

Furthermore this makes it easier to quickly identify false
positives, e.g. when a help message contains a Kconfig keyword
and falsely triggers checkpatch to stop counting lines,
it will be more apparent, because the user can see how many lines
they wrote and how many of those were counted correctly.
