Subject: [PATCH v2 ] net: phy: corrected the return value for genphy_check_and_restart_aneg 	and  genphy_c45_check_and_restart_aneg

When auto-negotiation is not required, return value should be zero.

Changes v1->v2:
- improved comments and code as Andrew Lunn and Heiner Kallweit suggestion
- fixed issue in genphy_c45_check_and_restart_aneg as Russell King
  suggestion.

Fixes: 2a10ab043ac5 ("net: phy: add genphy_check_and_restart_aneg()")
Fixes: 1af9f16840e9 ("net: phy: add genphy_c45_check_and_restart_aneg()")
