vgsp-gr r590b: the stream-order watermark must watch every ring, not engine_type!=0
The r591 draw reproduced the r568 signature (VADD bad=32735 csum=8139264,
c = a + 0) with ceback=0: the driver submits its relocation/H2D copies on
a COMPUTE channel (h=0x5c000059 registers eng=0), so the engine_type
filter skipped exactly the backlog the guard exists for.
Consider every other channel of the device (the launching channel is
excluded: its own ring legitimately runs ahead with future entries), and
read each one's live USERD GP_PUT against this pass's consumed position.
r590's validated part is unchanged: same pass snapshot, same bounded
defer, historical forward at the absolute cap (never a refusal).
