vgsp-sema: budget the data window - only real device operands get the full span
r141 showed the 68-pages-per-pointer change starved the operands: the
launch's own QMD VA (0x204608000) and other low-VA candidates each consumed
68 window pages, so a 256 KB operand resolved 0 pages before the 205-page
cap. Give the full span only to high, cudaMalloc-shaped VAs, skip the QMD
VA entirely, and give every other candidate one page. Three 256 KB operands
(3x68=204) now fit.
