esp.c: remove restriction on FIFO read access when DMA memory routines defined
The latest state machines can handle mixing DMA and non-DMA FIFO access for all
SCSI phases except DATA IN and DATA OUT. For DATA IN and DATA OUT phases, the
transfer is complete when TC == 0 and the updated logic will now handle TC
underflow correctly, which makes it just about impossible to manually manipulate
the FIFO during a DMA transfer.
Remove the restriction on FIFO read access when DMA memory routines are defined
which also allows the NeXTCube machine to pass its self-test.
