[PATCH v2 06/10] nl80211: Various checkpatch.pl spacing fixes

[Kirtika Ruchandani <kirtika.ruchandani@xxxxxxxxx>]

This patch fixes the following spacing issues reported
by checkpatch.pl -
- space preferred around that <operator>
- no space needed after cast.
- Alignment should match open parenthesis
- suspect code indent for conditional statements
- Statements should start on a tabstop

This patch also contains two hunks to fix 'line over 80 characters',
that are spacing related.
All other instances of that warning have been ignored.
