kernel: fn-10 delay tuned to 2ms (partial mitigation, not full fix)
2ms udelay before fn-10/47 replies. Mitigates but does not fully
eliminate the intermittent fn-10 FREE timeout (driver-side reply-
matching issue). Verified reply path correct: seqNum matches driver's
rxSeqNum (poison experiment 'Expected 75 got 175'), checksum folds to
0, function=10, writePtr/readPtr land, driver drains 1:1. Root cause
of the driver's intermittent non-acceptance of fn-10/47 replies during
cleanup remains under investigation (needs real-GSP oracle or guest-
kernel GDB inspection of the msgq reply-matching).
