vgsp-sema: discover GR data candidates from the fresh inline param block (second-client fix)
Second-client launches scanned a stale/reused guest param page that still
held the FIRST client's device VAs: zero new candidates resolved, nothing
was relocated, and the engine executed with unrelocated guest pointers
(r97 evidence: client#1 '15 candidate ptrs, 100 pages resolved' and win0
param 160=110400; client#2 '12 candidates, 1 page' with 160=75552ec00000
unrelocated). The driver-authored inline param block is captured from the
pushbuffer at request time, so scanning it makes pointer discovery
independent of guest-page reuse timing. Adds svc_gr_scan_cand()/
svc_gr_scan_inline() and the DIAG win0/guest-param proof line. Client #1
stays green (4 cycles); the remaining second-client stall is the pool
semaphore residue (see next commit).
