Subject: [PATCH v2] staging: wilc1000: correct inconsistent indenting

Correct inconsistent indenting reported by smatch.
Instead of simply remove indentation, refactor the
loop to also improve readabilitiy.

Suggested-by: Joe Perches <joe@...ches.com>
Signed-off-by: Michael Straube <straube.linux@...il.com>

v1 -> v2
Refactor loop instead of simply remove indentation
as suggested by Joe Perches.
