[PATCH 4/4] iw: scan: fixup HE caps whitespace

[Brian Norris <briannorris@chromium.org>]

For scans, it's nicer to drop an indentation level, because we don't
have the "interface type" section that we do in the phy-info version.

The NSS print also had an extra level of indentation, and a spare
leading space, which made it a bit inconsistent with other sections.
