[Intel-gfx] [PATCH v2 06/15] drm/i915/buddy: tweak 2big check

[Matthew Auld]

Otherwise we get -EINVAL, instead of the more useful -E2BIG if the
allocation doesn't fit within the pfn range, like with mappable lmem.
The hugepages selftest, for example, needs this to know if a smaller
size is needed.
