Fix potential driver lockup problem Since we have already store the inta to priv->isr_inta in the interrupt handler we don't need to get it from the hardware again in the tasklet. Some people find ipw3945-1.2.1 still didn't resolve the boot lockup problem as reported in bugzilla #1096. If you still find the lockup problem in ipw3945-1.2.1, please try this patch and report if it resolves your problem or not to yi.zhu@intel.com. Thanks to Egon for providing this patch!
