fpga: stratix10-soc: fix use-after-free on s10_init()
The refcount of fw_np has already been decreased by of_find_matching_node()
so it shouldn't be used anymore.
This patch adds an of_node_get() before of_find_matching_node() to avoid
the use-after-free problem.
Fixes: e7eef1d7633a ("fpga: add intel stratix10 soc fpga manager driver")
