mt76: fix a leaked reference by adding a missing of_node_put



[ Upstream commit 34e022d8b780a03902d82fb3997ba7c7b1f40c81 ]

The call to of_find_node_by_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

Detected by coccinelle with the following warnings:
