[PATCH 2.6.37] led_class: fix typo in blink API

[Johannes Berg <johannes@sipsolutions.net>]

From: Johannes Berg <johannes.berg@intel.com>

When I added led_blink_set I had a typo: the
return value of the hw offload is a regular
error code that is zero when succesful, and
in that case software emulation should not
be used, rather than the other way around.

It'd be nice to get this into 2.6.37 since the patch
that has the bug is in there. Sorry about that -- I
had tested the software implementation extensively but
apparently never tested the hw offload part.
