i915: move the FALLBACK_DRAW_OFFSET check outside the drawing rect check

Browse source 
We have to do fallback when the 'Clipped Drawing Rectangle X/Y Max'
exceed the hardware's limit no matter the drawing rectangle offset
changed or not.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=46665

NOTE: This is a candidate for stable release branches.
