usb: fix cleanup after failure in hub_configure()
commit d0308d4b6b02597f39fc31a9bddf7bb3faad5622 upstream.
If the hub_configure() fails after setting the hdev->maxchild
the hub->ports might be NULL or point to uninitialized kzallocated
memory causing NULL pointer dereference in hub_quiesce() during cleanup.
Now after such error the hdev->maxchild is set to 0 to avoid cleanup
of uninitialized ports.
