Revert "net: gem: Disable broadcast setting"

This reverts commit eafdcda4a854932c0319656de7bf3f017f17ae67.

The main reason is that QEMU is using BOOTP protocol which is sending DHCP
Offer to a broadcast address that's why it can't be disabled.
DHCP protocol has no issue because it returns directly to client MAC
address.
Both of these options are described in RFC951
(https://datatracker.ietf.org/doc/html/rfc951#section-4)
