Subject: [PATCH net v2 5/9] net/macmace: Fix and cleanup log messages

Log the MAC address after the interface gets a meaningful name
and in doing so, make the registration error path more idiomatic.
Drop redundant debug messages for FIFO events recorded in the
interface statistics (consistent with mace.c).
