pppoe: fix use-after-free in mac_filter_load()
When a mac-filter file line contained an octet > 255, the error path freed
the entry but kept writing to it and linked it into mac_list. Validate all
octets before allocating so invalid lines are skipped entirely.
This is not considered a security vulnerability: the mac-filter file can
only be configured by an administrator with access to the daemon config,
or the CLI, both of which require privileged access.
Fixes #307
