Jan Beulich f1d20d8643 Xen/gntdev: don't needlessly use kvcalloc() 
Requesting zeroed memory when all of it will be overwritten subsequently
by all ones is a waste of processing bandwidth. In fact, rather than
recording zeroed ->grants[], fill that array too with more appropriate
"invalid" indicators.
