firewire: Change struct fw_cdev_iso_packet to not use bitfields.
The struct is part of the userspace interface and can not use bitfields. This patch replaces the bitfields with a __u32 'control' word and provides access macros to set the bits. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
