staging/slicoss: Fix operation may be undefined warning
gcc complains about an undefined operation:
slicoss.c:1417:19: warning: operation on 'rspq->pageindex' may be
undefined [-Wsequence-point]
The intended operation was (probably) to retrieve the pageindex + 1 and let
it wrap around if it reaches the num_pages.
