arm64: vdso: Mark vdso_pagelist allocation as not a leak

The vdso_pagelist allocation is stored inside the vDSO mappings, which
are static, so the memory is never leaked. However, kmemleak thinks that
vdso_pagelist is leaked because the vDSO mappings are read-only after
init.

Fix kmemleak's false positive by marking the allocation as not a leak.
