Do not use a random FW_CDEV_VERSION as our implemented ABI version
Since linux/firewire-cdev.h header file and libraw1394 sources are
distributed separately, it is wrong to fill in a constant from that
header into the FW_CDEV_IOC_GET_INFO ioctl as the ABI version which
libraw1394 supports. This may not be forward compatible if an old
libraw1394 is compiled with a new kernel header and ran on top of a
kernel that implements new features that require a compatible
userland.
OK, the damage is already done in released versions of libraw1394.
Hence the FW_CDEV_VERSION of the kernel header file is not going to
be updated anymore in future kernel versions. (Only the version
internally to firewire-core will be incremented further.)
But let's remove the buggy usage of FW_CDEV_VERSION nevertheless.
Developers of other firewire-cdev client programs might look at
libraw1394 sources. The libraw1394 sources should not teach them
how to do it wrong.
