Log Message:
Don't let the chan_qfreeze count go negative.

It's possible that the adapters shouldn't do this. But if you think about
it, this is a function that could be called from anywhere. In any case,
the specific reason here was that there is *sometimes* one more Loop UP
message from QLogic FC cards than then Loop Down, so making the chan_qfreeze
go negative blocked the queue needlessly.

Add a splbio/splx around the test against XS_STS_DONE in scsipi_execute_xs
for the non-async case so we don't do the classic sleep after test crock.
