drm/buddy: fix range bias
There is a corner case here where start/end is after/before the block
range we are currently checking. If so we need to be sure that splitting
the block will eventually give use the block size we need. To do that we
should adjust the block range to account for the start/end, and only
continue with the split if the size/alignment will fit the requested
size. Not doing so can result in leaving split blocks unmerged when it
eventually fails.
Fixes: afea229fe102 ("drm: improve drm_buddy_alloc function")
