Juergen Gross 239af7c713 x86/xen: avoid writing to freed memory after race in p2m handling 
In case a race was detected during allocation of a new p2m tree
element in alloc_p2m() the new allocated mid_mfn page is freed without
updating the pointer to the found value in the tree. This will result
in overwriting the just freed page with the mfn of the p2m leaf.
