[PATCH] fs/jffs2: kill warning RE debug-only variables

[Jeff Garzik]

gcc emits the following warning on a 'allmodconfig' build:

fs/jffs2/xattr.c: In function âunrefer_xattr_datumâ:
fs/jffs2/xattr.c:402: warning: unused variable âversionâ
fs/jffs2/xattr.c:402: warning: unused variable âxidâ

Given that these variables are only used in the debug printk, and they
merely remove a deref, we can easily kill the warning by adding the
derefs to the debug printk.
