V4L/DVB (6125): whitespace cleanup: replace leading spaces with tabs

There were many instances of 7-space indents spread throughout
the v4l-dvb tree.

This patch replaces the 7-space indents with tabs.  The whitespace cleaner
script doesn't catch these, because it assumes that all indents are 8-space.
