net: enetc: do not print error log if addr is 0

Browse Source 
A value of 0 for addr indicates that the IEB_LBCR register does not
need to be configured, as its default value is 0. However, the driver
will print an error log if addr is 0, so this issue needs to be fixed.

Fixes: 50bfd9c06f0f ("net: enetc: set external PHY address in IERB for i.MX94 ENETC")
