[PATCH 2/3] xen/x86: free_p2m_page: use memblock_free_ptr() to free a virtual pointer

[Mike Rapoport <rppt@xxxxxxxxxx>]

From: Mike Rapoport <rppt@xxxxxxxxxxxxx>

free_p2m_page() wrongly passes a virtual pointer to memblock_free() that
treats it as a physical address.

Call memblock_free_ptr() instead that gets a virtual address to free the
memory.
