[PATCH] compat-wireless: fix debugging in iwlwifi

[Johannes Berg <johannes@sipsolutions.net>]

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

As compat includes linux/device.h well before iwlwifi, the
definitions from there are used without DEBUG, but iwlwifi
defines DEBUG to get debug output. Use dev_printk instead
of dev_dbg to get debugging back.

+Due to compat including linux/device.h before we do,
+we don't get a chance to #define DEBUG to get our
+debugging prints. This patch replaces dev_dbg with
+dev_printk to make them show up again.
