samples/vfio-mdev/mdpy: use remap_vmalloc_range 

Patch series "remap_vmalloc_range cleanups".

This series removes an open coded instance of remap_vmalloc_range and
removes the unused remap_vmalloc_range_partial export.

This patch (of 2):

Use remap_vmalloc_range instead of open coding it using
remap_vmalloc_range_partial.
