For vmx domain, because shadow_mode_reference is set later in
vmx_final_setup_guest, so in arch_set_info_guest, the phys_basetab
is not do get_page, while when destroying, put_page is called,
so there is one page, the count=-1, and when a new domain allocate
this page, it will take it as cpumask 0xffffffff, this cause flash_tlb_mask
goes into dead loop.
This patch also eliminate the warning when creating vmx guest:
(XEN) Audit 1: type count went below zero mfn=1e03d t=f0000000 ot=3654b
