net: ethernet: renesas: rswitch: Fix error path in renesas_eth_sw_probe()
If rswitch_init() returns non-zero and this driver is re-probed,
the following error happens:
renesas_eth_sw e6880000.ethernet: Unbalanced pm_runtime_enable!
So, fix error path in renesas_eth_sw_probe().
Fixes: 3590918b5d07 ("net: ethernet: renesas: Add support for "Ethernet Switch"")
