Haoxiang Li 22e4977141 rapidio: fix an API misues when rio_add_net() fails ...

commit b2ef51c74b upstream.

rio_add_net() calls device_register() and fails when device_register()
fails.  Thus, put_device() should be used rather than kfree().  Add
"mport->net = NULL;" to avoid a use after free issue.
