tap: Use different io vector bases depending on tap type

Currently tap_send_frames() expects the frames it is given to include the
vnet_len field, even in pasta mode which doesn't use it (although it need
not be initialized in that case).  To match, tap_iov_base() and
tap_iov_len() construct the frame in that way.

This will inconvenience future changes, so alter things to set the buffers
to include just the frame needed by the tap backend type.
