tap: Extend tap_send_frames() to allow multi-buffer frames

tap_send_frames() takes a vector of buffers and requires exactly one frame
per buffer.  We have future plans where we want to have multiple buffers
per frame in some circumstances, so extend tap_send_frames() to take the
number of buffers per frame as a parameter.
