ACPI: x86: s2idle: Post-increment variables when getting constraints

[ Upstream commit 3c6b1212d20bbbffcad5709ab0f2d5ed9b5859a8 ]

When code uses a pre-increment it makes the reader question "why".
In the constraint fetching code there is no reason for the variables
to be pre-incremented so adjust to post-increment.
No intended functional changes.
