summary:     hvm: Remove duplicate assignment of __HYPERVISOR_grant_table_op in

Has broken our HVM PV drivers. Previously we were using:

520         if ((HYPERVISOR_grant_table_op(GNTTABOP_setup_table, pset, 1) != 0) 
||
521             (pset->status != 0)) { 

even on HVM. Now, this isn't actually necessary (stuff works fine with
the call nop'd out, presumably due to the auto-sizing), but I wonder why the
only grant op allowed is _query_size? IE what's the status of grant
table code on HVM/PV? Is it just disabled because no compat audit has
been done, or what?

regards
john
