media: uvcvideo: Fix uvc_alloc_entity() allocation alignment
The use of ALIGN() in uvc_alloc_entity() is incorrect, since the size of
(entity->pads) is not a power of two. As a stop-gap, until a better
solution is adapted, use roundup() instead.
Found by a static assertion. Compile-tested only.
Fixes: 4ffc2d89f38a ("uvcvideo: Register subdevices for each entity")
