simplify some logic in ext4_mb_normalize_request
While reading through some of the mballoc code it seems that a couple spots in the size normalization function could be streamlined. The test for non-overlapping PAs can be or'd for the start & end conditions, and the tests for adjacent PAs can be else-if'd - it's essentially independently testing: if (A + B <= C) ... if (A > C) ... These cannot both be true so it seems like the else-if might be slightly more efficient and/or informative.
