QLowEnergyControllerPrivateWinRT::connectToDevice: Return early if LE device cannot be found
If the host does not support BTLE, connectToDevice will fail and mDevice
will be zero. The return in this case was missing so that we tried to
access a null pointer and caused an exception.
(cherry picked from commit 280cfd43012d1cfbfcd26fe57f633db3fc13a379)
