phy: phy-ocelot-serdes: fix return value check in serdes_probe()
In case of error, the function syscon_node_to_regmap() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
Fixes: 51f6b410fc22 ("phy: add driver for Microsemi Ocelot SerDes muxing")
