esp-scsi: handle non-DMA SCSI commands with no data phase
The existing esp-scsi state machine checks for the STAT_TC bit to exit state 1
but in the case where there is no data phase, a non-DMA command is executed
which doesn't set STAT_TC. This only works because QEMU currently always sets
STAT_TC just after issuing every SCSI command.
Update the esp-scsi state machine so that in the case where there is no data
phase, we immediately execute CMD_ICCS instead of waiting for STAT_TC to be
set which will never happen with a non-DMA CMD_SELATN command.
