	syssrc/sys/arch/sgimips/hpc: if_sq.c

Log Message:
Fix a deadlock in the tx code -- the code checked the DMA status before
sync'ing the descriptor, leading to a race where the packet could complete
after the DMA check but before the sync of the descriptor, sending the code
into unknown territory and the DMA engine into space.  Also, fix a bug with
spurious watchdog resets going off due to the if_timer not always being set
on transmit.

Finally, clean up use of hardcoded magic numbers, get them from hpcreg.h
when possible.
