Liam R. Howlett 7ccf089b26 xen: use vma_lookup() in privcmd_ioctl_mmap() ...

vma_lookup() walks the VMA tree for a specific value, find_vma() will
search the tree after walking to a specific value.  It is more efficient
to only walk to the requested value since privcmd_ioctl_mmap() will exit
the loop if vm_start != msg->va.
