[18/54] iwlwifi: fix TX tracer

[Greg KH]

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit e95b743536937a72e1560c85696b425c5d1a1c18 upstream.

The TX tracing code copies with the wrong length,
which will typically copy too little data. Fix
this by using the correct length variable.
