Log Message:
Fix M_PKTHDR use in if_alc, if_age and if_ena.
if_alc and if_age always put in _rxhead a M_PKTHDR-flagged mbuf, so the
flag must always be present. Instead of manually adding the flag, add a
KASSERT to ensure it is already there. If it weren't, there would be
memory corruptions.
Same in if_ena, but this one does not compile so we don't really care.
Also, use m_remove_pkthdr to remove the flag, instead of doing it
manually. This ensures the tags get freed (even though these drivers
don't seem to be using mtags).
