Miaoqian Lin 2844c564a0 media: renesas: rcar_drif: fix device node reference leak in rcar_drif_bond_enabled ...

commit 445e165889 upstream.

The function calls of_parse_phandle() which returns
a device node with an incremented reference count. When the bonded device
is not available, the function
returns NULL without releasing the reference, causing a reference leak.

Add of_node_put(np) to release the device node reference.
The of_node_put function handles NULL pointers.

Found through static analysis by reviewing the doc of of_parse_phandle()
and cross-checking its usage patterns across the codebase.
