iwlwifi: disable interrupts before calling request_irq
Disable interrupts in the iwl4965 before calling request_irq() for the case that the previous OS or the BIOS left a pending interrupt in the chip. This behavior has been observed on some laptops such as T61 Thinkpads and Toshiba Portege R500 Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
