Summary

The only caller udp_send() has already entered net epoch before invoking
udp_v4mapped_pktinfo().

No functional change intended.

This partially reverts commit d74b7baeb0d4 (ifnet_byindex() actually
requires network epoch).

Didn't do a full examination of all stacks, the change by itself should be correct. If any code path triggers the new assertion, that path needs to be fixed.
