Tvrtko Ursulin 206fa92c9d drm/i915: Relax mmap VMA check 
[ Upstream commit ca22f32a62 ]

Legacy behaviour was to allow non-page-aligned mmap requests, as does the
linux mmap(2) implementation by virtue of automatically rounding up for
the caller.

To avoid breaking legacy userspace relax the newly introduced fix.
