octeon_ep: ensure get mac address successfully before eth_hw_addr_set()
octep_get_mac_addr() can fail because send mbox message failed. If this
happens, octep_dev->mac_addr will be zero. It should not continue to
initialize. Add exception handling for octep_get_mac_addr() to fix it.
Fixes: 862cd659a6fb ("octeon_ep: Add driver framework and device initialization")
