[PATCH] net: phy: mscc: fix ptr_ret.cocci warnings

[kernel test robot]

From: kernel test robot <lkp@xxxxxxxxx>

drivers/net/phy/mscc/mscc_ptp.c:1496:1-3: WARNING: PTR_ERR_OR_ZERO can be used


 Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR

Generated by: scripts/coccinelle/api/ptr_ret.cocci
