[PATCH] compat-wireless: Handle name change from iwlagn to iwlwifi in 3.2

[Don Fry <donald.h.fry@intel.com>]

From: Don Fry <donald.h.fry@intel.com>

With linux-3.2 the iwlagn driver is renamed iwlwifi.  For some kernels
(like 3.1.5) this causes the non-compat iwlagn.ko to try and run against
the compat mac80211 resulting in an oops.  This change prevents the
non-compat iwlagn.ko from being loaded.
