drm/i915: Skip stolen region initialisation if none is reserved

Paulo reported that if he set the amount of reserved memory to 0, then
we emitted a warning about a conflict before disabling our use of stolen
memory. This was introduced with

commit eaba1b8f3379b5d100bd146b9a41d28348bdfd09

    drm/i915: Verify that our stolen memory doesn't conflict

and is simply fixed by checking for a no reservation first.
