always clear the X2APIC_ENABLE bit for PV guest
[ Upstream commit 5268c8f39e0efef81af2aaed160272d9eb507beb ]
Commit e657fcc clears cpu capability bit instead of using fake cpuid
value, the EXTD 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.
