Current mtrr_commit() logic assumes that MTRR MSRs are programmed consecutively from index 0 to its maximum number, and whenever it detects an unused one, it clears all other MTRRs starting from that one. However this may not always be the case.
In fact, the clear is not much helpful because these MTRRs come out of reset as disabled already. Drop the clear codes.
