firewire: cdev: reduce stack usage by ioctl_dispatch
Replace a hardcoded buffer size by a sizeof union {}. This shrinks the
stack-allocated ioctl argument buffer from 256 to 40 bytes. (This is
not much, but subsequent stack usage particularly by the queue_iso ioctl
handler adds up.)
The new form is also easier to keep up to date than a hardcoded size if
more ioctls are added.
