pstore/ram: Fix error return code in ramoops_probe()
[ Upstream commit e1fce564900f8734edf15b87f028c57e14f6e28d ]
In the if (dev_of_node(dev) && !pdata) path, the "err" may be assigned a
value of 0, so the error return code -EINVAL may be incorrectly set
to 0. To fix set valid return code before calling to goto.
