udp: Preadjust udp[46]_l2_iov_tap[].iov_base for pasta mode
Currently, we always populate udp[46]_l2_iov_tap[].iov_base with the
very start of the header buffers, including space for the qemu vnet_len
tag suitable for passt mode. That's ok because we don't actually use these
iovecs for pasta mode.
However, we do know the mode in udp_sock[46]_iov_init() so adjust these
to the beginning of the headers we'll actually need for the mode: including
the vnet_len tag for passt, but excluding it for pasta.
This allows a slightly nicer way to locate the right buffer to send in the
pasta case, and will allow some additional cleanups later.
