vgsp-sema: SESSION 134b fix the CE first-submission scan's entry decode (u32 hva truncated the 40-bit VA so no CE-window entry could ever match)
hva must hold the 40-bit push VA (bit 32 set for the CE window) but was
declared u32 in the scan, so ((h1 & 0xff) << 32) truncated to the low
dword and hva < 0x120000000ULL was always true - scan_hits stayed 0 by
construction. Same decode as svc_chan_userd/svc_gr_ring_candidate (u64).
Verified building; the FB-convention latch itself (auto-pinned ring
h=0xcaf00012 -> fb 0x80000, userd 0x90000, entry decode + push decode,
ops_runs=1) was observed independently on r776.
