Log:
xen: init gnttab from xenpv
Currently the grant table is initialized from xenstore, but a better
place to do this would be xenpv, so move grant table initialization
there.
Sponsored by: Citrix Systems R&D
Approved by: gibbs
x86/xen/xenpv.c:
- Add gnttab initialization.
xen/xenstore/xenstore.c:
- Remove gnttab initialization.
