MINOR: muxes/h1-htx: Realign input buffer using b_slow_realign_ofs()

Input buffers have never output data. So, use b_slow_realign_ofs() function
instead of b_slow_realign(). It is a slighly simpler function. And in the H1
mux, it allows a realign by setting the input buffer head to permit
zero-copies.
