USB: cdc-wdm: call wake_up_all to allow driver to shutdown on device removal
commit 62aaf24dc125d7c55c93e313d15611f152b030c7 upstream.
wdm_disconnect() waits for the mutex held by wdm_read() before
calling wake_up_all(). This causes a deadlock, preventing device removal
to complete. Do the wake_up_all() before we start waiting for the locks.
