iwlagn: workaround bug crashing some APs
commit 2249b011432ca3dcce112f0f71e0f531b4bb9347 upstream.
This patch reverts commit 9b7688328422b88a7a15dc0dc123ad9ab1a6e22d which
was introduced in 2.6.38-rc1. It works around a problem where the iwlagn
driver stimulates a bug crashing (requiring power cycle to recover) some
APs under heavy traffic.
