kernel: fn-10 timing-race mitigation (2ms reply delay) + remove seqNum-poison
The fn-10 FREE timeout is a driver-side reply-matching TIMING RACE, not
a content bug. seqNum-poison experiment PROVED the driver's rxSeqNum
matches our stat_seq exactly ('Expected 75 got 175'); checksum folds to
0; function=10; writePtr/readPtr land; driver drains 1:1. A 2ms udelay
before fn-10/47 replies eliminates timeouts in most runs (matches real
GSP-RM's natural reply latency). Removed the seqNum-poison diagnostic
(served its purpose) and fn10 wire-bytes debug dumps. Race is not 100%
eliminated - intermittently recurs during unload/cleanup cycles.
