net: phy: make phy_error() report which PHY has failed

phy_error() is called from phy_interrupt() or phy_state_machine(), and
uses WARN_ON() to print a backtrace. The backtrace is not useful when
reporting a PHY error.

However, a system may contain multiple ethernet PHYs, and phy_error()
gives no clue which one caused the problem.

Replace WARN_ON() with a call to phydev_err() so that we can see which
PHY had an error, and also inform the user that we are halting the PHY.
