usb: gadget: f_mbim: Queue notification request upon function resume
In super speed mode if userspace issues a write after usb bus suspend
usb_func_ep_queue() schedules wakeup to resume the function. After that
it queues the request which fails with -ENOTSUPP. As a result no
notification request queued to hw and write request gets delayed to be
sent until another write request comes and queues notification request
after function resume. This causes mismatch to the mbim request response.
Fix this by queuing the notification request upon function resume if
notify count is greater than zero. Also, drop control packet after bus
suspend if remote wakeup is not supported or if ep enqueue returns error
other than -EAGAIN.
