There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().
The usage pattern of the completion is:
waiter context waker context
reinit_completion()
usb_esp_queue()
wait_for_completion_interruptible()
ffs_ep0_complete()
complete()
