esp.c: remove MacOS TI workaround that pads FIFO transfers to ESP_FIFO_SZ
This workaround is no longer required with the current code and so can be
removed.
[Note: whilst MacOS itself can boot correctly, removing this hack prevents
a bootable EMILE CDROM from working. This is caused by a separate bug which
will be fixed by a subsequent patch]
