When the diver is removed and all the resources are deallocated,
we should be iterating through the created devices only.
Currently, the iteration ends when vivid_devs[i] is NULL. Since
the array contains VIVID_MAX_DEVS elements, it will oops if
n_devs=VIVID_MAX_DEVS because in that case, no element is NULL.
