[PATCH] firewire: core: fix build failure due to the caller of fw_csr_string()

[Takashi Sakamoto]

A commit 47dc55181dcb ("firewire: core: search descriptor leaf just after
vendor directory entry in root directory") for v6.8-rc3 and a commit
67a5a58c0443 ("firewire: Kill unnecessary buf check in
device_attribute.show") for v6.9 bring build failure in for-next tree due
to the change of the name of local variable.

This commit fixes it.
