media: v4l: ioctl: Use kmalloc to allocate a small chunk of memory
kvmalloc() was used to allocate the temporary memory buffer that was used to contain both the IOCTL argument as well as a possible array argument that could have been large. Now that the two are separated, the IOCTL argument is known to be small in size. Use kmalloc to allocate it instead of kvmalloc. Similarly for releasing it.
