Commit e657fcc clears cpu capability bit instead of using fake cpuid
value, the EXID should always be off for PV guest without depending
on cpuid value. So remove the cpuid check in xen_read_msr_safe() to
always clear the X2APIC_ENABLE bit.

This errata affect the values read from the BAR registers, and could
render vPCI (and by extension PVH Dom0 unusable).
HSE43 is a Haswell erratum where a non-BAR register is implemented at
the position where the first BAR of the device should be found in a
Power Control Unit device. Note that ther
