    drm/i915: Use expcitly fixed type in compat32 structs

changed the type of param field in drm_i915_getparam from int to
s32. This header is exported to userspace and needs to use userspace
type __s32 instead.

This fixes userspace compilation errors like the following:
include/drm/i915_drm.h:361:2: error: unknown type name 's32'
  s32 param;
