Treat mbufs as cacheline-aligned.  Even when the transfer begins at an
offset within the buffer to align the L3 headers we know the buffer itself
was allocated and sized on cacheline boundaries and we don't need to
preserve partitial cachelines at the start and end of the buffer when
doing busdma sync operations.
