vgsp-gr r598 diag: peek the ring slots past GP_PUT at the launch decision
The r568 lever is the driver's ring WRITE pointer, not the GPFIFO put:
the b copy entry exists in the ring before the client publishes GP_PUT.
Add a bounded diagnostic (gsp_phys_gr_peek) that, when a channel reads
as drained, dumps up to four slots past last_get with {va,len} and
whether the slot already executed that exact entry - so the next fix can
be grounded in what is actually written ahead of the put.
