target-i386: Mask mtrr mask based on CPU physical address limits

The CPU GPs if we try and set a bit in a variable MTRR mask above
the limit of physical address bits on the host.  We hit this
when loading a migration from a host with a larger physical
address limit than our destination (e.g. a Xeon->i7 of same
generation) but previously used to get away with it
until 48e1a45 started checking that msr writes actually worked.

It seems in our case the GP probably comes from KVM emulating
that GP.
