    vscsiif.h: replace PAGE_SIZE with VSCSIIF_PAGE_SIZE
    
    Do not reference PAGE_SIZE directly: it could be undefined, or it could
    have different values in the frontend or in the backend.
    
    Define VSCSIIF_PAGE_SIZE as 4096, assuming all users of vscsiif.h have
    4K page granularity. Replace PAGE_SIZE with VSCSIIF_PAGE_SIZE.
