iflib: Add null check to iflib_stop()
Ever since gtaskqueue_drain() was added to iflib_stop(), a kernel panic occurs when the ice(4) driver is in recovery mode. Queues are not initialized in this mode, so gt_taskqueue is not initialized, and gtaskqueue_drain() will panic. Fix this by only doing a drain if an RX queue's gt_taskqueue is initialized.
