    gnttab: remove gnttab_alloc_and_grant() function
    
    The last user of gnttab_alloc_and_grant() is gone.
    
    Remove gnttab_alloc_and_grant() as it is doing more harm than good.
    It is hard coded to only grant access for dom0, which is not really
    clear from looking at the function name. It would be possible to add
    a domid parameter, but given its now 0 users, there doesn't seem to be
    a real demand for that function.
