xen/privcmd: Optimized privcmd_ioctl_mmap() by using vma_lookup()

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 as this case requires the address to
equal the vm_start.
