Michael Kelley 25727aaed6 hv_netvsc: Remove second mapping of send and recv buffers
With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), creating a second kernel virtual
mapping for shared memory is no longer necessary.  Everything needed
for the transition to shared is handled by set_memory_decrypted().

As such, remove the code to create and manage the second
mapping for the pre-allocated send and recv buffers.  This mapping
is the last user of hv_map_memory()/hv_unmap_memory(), so delete
these functions as well.  Finally, hv_map_memory() is the last
user of vmap_pfn() in Hyper-V guest code, so remove the Kconfig
selection of VMAP_PFN.
