x86/mm/mtrr: Remove incorrect address check in __mtrr_type_lookup()

__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 an
incorrect 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 incorrect address check with 'else' with no
condition.
