CHROMIUM: net: ipw2x00: #ifdef condtionally used variable

The variable 'dev' is only used by a macro LIBIPW_DEBUG_WX() that is
conditional upon the config option 'CONFIG_LIBIPW_DEBUG'.  When this
config option isn't defined, we get this warning:

  libipw_wx.c:526:21: error: unused variable 'dev'

The solution is to define 'dev' only if CONFIG_LIBIPW_DEBUG is defined.

BUG=chromium-os:5542
TEST=emerge-x86-generic chromeos-kernel, make sure warning doesn't
appear.
