firewire: core: fix overlooked update of subsystem ABI version

[ Upstream commit 853a57ba263adfecf4430b936d6862bc475b4bb5 ]

In kernel v6.5, several functions were added to the cdev layer. This required updating the default version of subsystem ABI up to 6, but this requirement was overlooked.

This commit updates the version accordingly.

Fixes 6add87e9764d ("firewire: cdev: add new version of ABI to notify time stamp at request/response subaction of transaction#")
