From: Zijun Hu <quic_zijuhu@quicinc.com>

bcmasp_probe() invokes of_find_node_by_name(@dev->of_node, ...) and the
callee will put OF device node @dev->of_node refcount, but the caller
does not compensate the refcount before the invocation, so causes the node
refcount leakage.

Fix by of_node_get(@dev->of_node) before the invocation.

Fixes: 490cb412007d ("net: bcmasp: Add support for ASP2.0 Ethernet controller")
