Fifo reading might stuck depending on AHB

[M0stafaRady]

Since reading from the fifo is dependent on the value of last_HTRANS, if the of last_HTRANS didn't get updated because HREADY is deasserted the fifo would keep popping values until HREADY is asserted. The dependency over HREADY should be removed somehow.
