Fix slow CAR execution introduced by 7c7d87182feb78cb2bc02fb3558bef56a41682c9

It is meant to be a address and not a dereference. Otherwise MTRR
is filled with code and not with the address.

This is what I hate at most on the AT&T syntax. Instead of taking
the address, it was a dereference. Not greatly visible, except
I wondered why opcode is not 0xb4 but 0xa1 and it took another
half an our to see it.
