__mtrr_type_lookup() checks MTRR fixed ranges when mtrr_state.have_fixed is set and start is less than 0x100000. However, the 'else if (start < 0x1000000)' in the code checks with a wrong address as it has an extra-zero in the address. The code still runs correctly as this check is meaningless, though.
This patch replaces the wrong address check with 'else' with no condition.
