Subject: [media] vivid: Fix iteration in driver removal path

From: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar>

commit a5d42b8c3b3ddccd88dc1c70957177d31a6699fb upstream.

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.

Fixes: c88a96b023d8 ('[media] vivid: add core driver code')
