usb: musb: Fix host mode error -71 regression
Commit 467d5c980709 ("usb: musb: Implement session bit based runtime PM for musb-core") started implementing musb generic runtime PM support by introducing devctl register session bit based state control. This caused a regression where if a USB mass storage device is connected to a USB hub, we can get: usb 1-1: reset high-speed USB device number 2 using musb-hdrc usb 1-1: device descriptor read/64, error -71 usb 1-1.1: new high-speed USB device number 4 using musb-hdrc This is because before the USB storage device is connected, musb is in OTG_STATE_A_SUSPEND. And we currently only set need_finish_resume in musb_stage0_irq() and the related code calling finish_resume_work in musb_resume() and musb_runtime_resume() never gets called. To fix the issue, we can call schedule_delayed_work() directly in musb_stage0_irq() to have finish_resume_work run. And we should no longer never get interrupts when when suspended. We have changed musb to no longer need pm_runtime_irqsafe(). The need_finish_resume flag was added in commit 9298b4aad37e ("usb: musb: fix device hotplug behind hub") and no longer applies as far as I can tell. So let's just remove the earlier code that no longer is needed.
