Colin Percival d262f2dcfc Make i386_set_ldt work on i386/XEN, step 1/5.
Lock the vm page queue mutex around calls to pte_store.  As with many other
uses of the vm page queue mutex in i386/xen/pmap.c, this is bogus and needs
to be replaced at some future date by a spin lock dedicated to protecting
the queue of pending xen page mapping hypervisor calls.  (But for now, bogus
locking is better than a panic.)
