Some old changes I forgot to commit... BInputServerDevice::InitCheck()

now checks if the fOwner allocation went fine (and returns B_NO_MEMORY 
in case it didn't). Since it can fail, inherited classes should call it 
as well (I modified MouseInputDevice's and KeyboardInputDevice's 
versions for now)
