Subject: [PATCH v3 5/5] staging: vme_user: Use dev_err() in vme_check_window()

vme_check_window() uses printk() for logging error message. This
leads to the following checkpatch warning:
   WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then
            dev_err(dev, ... then pr_err(...  to printk(KERN_ERR ...

Use dev_err() instead. Pass VME bridge device to vme_check_window() so
that the error message can be logged with the bridge device context.
