When probing for devices, clover will call pipe_loader_probe() twice.
The first time to retrieve the number of devices, and then second time
to retrieve the device structures.
We currently assume that the return value of both calls will be the
same, but this will not be the case if a device happens to disappear
between the two calls.
This patch removes this assumption and checks the return value of the
second pipe_loader_probe() call to ensure it does not try to initialize
devices that no longer exits.
