iwl3945: disable hw scan by default
commit 0263aa45293838b514b8af674a03faf040991a90 upstream.
After new NetworkManager 0.8.996 changes, hardware scanning is causing
microcode errors as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=683571
and sometimes kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=688252
Also with hw scan there are very bad performance on some systems
as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=671366
Since Intel no longer supports 3945, there is no chance to get proper
firmware fixes, we need workaround problems by disable hardware scanning
by default.
