Neeraj Upadhyay a4ede46647 PM: sleep: wakeup: Skip wakeup_source_sysfs_remove() if device is not there ...

commit 87de6594dc upstream.

Skip wakeup_source_sysfs_remove() to fix a NULL pinter dereference via
ws->dev, if the wakeup source is unregistered before registering the
wakeup class from device_add().

Fixes: 2ca3d1ecb8 ("PM / wakeup: Register wakeup class kobj after device is added")
