Jon Hunter 7c70fbf0cf misc: bluedroid_pm: Verify wakeup registration ...

The structure returned from the function wakeup_source_register() is not
currently checked to see that a valid structure is returned. If
wakeup_source_register fails to register the wake-up source, then this
function will return a NULL pointer and this will lead to a crash when
defereferencing this pointer. Therefore, check that a valid structure is
returned from wakeup_source_register() and if not then return an error
from the probe function.
