tap: Remove unhelpeful vnet_pre optimization from tap_send()
Callers of tap_send() can optionally use a small optimization by adding
extra space for the 4 byte length header used on the qemu socket interface.
tap_ip_send() is currently the only user of this, but this is used only
for "slow path" ICMP and DHCP packets, so there's not a lot of value to
the optimization.
Worse, having the two paths here complicates the interface and makes future
cleanups difficult, so just remove it. I have some plans to bring back the
optimization in a more general way in future, but for now it's just in the
way.
