staging: vme_user: Remove printk() in find_bridge()

Don't log error message in find_bridge(). The printk() triggers a
checkpatch warning:
    WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then
             dev_err(dev, ... then pr_err(...  to printk(KERN_ERR ...

It can't be replaced by dev_err() & using pr_err() is not helpful as it
doesn't give much context to the user. It is better to remove it.
