net: airoha: fix potential use-after-free in airoha_npu_get()
[ Upstream commit 3cd582e7d0787506990ef0180405eb6224fa90a6 ]
np->name was being used after calling of_node_put(np), which
releases the node and can lead to a use-after-free bug.
Previously, of_node_put(np) was called unconditionally after
of_find_device_by_node(np), which could result in a use-after-free if
pdev is NULL.
This patch moves of_node_put(np) after the error check to ensure
the node is only released after both the error and success cases
are handled appropriately, preventing potential resource issues.
