[IA64] pv_ops: fix ivt.S paravirtualization

Recent kernels are not booting on some HP systems (though
it does boot on others). James and Willy reported the
problem.  James did the bisection to find the commit
that caused the problem:
	498c5170472ff0c03a29d22dbd33225a0be038f4.
	[IA64] pvops: paravirtualize ivt.S

Two instructions were wrongly paravirtualized such that
_FROM_ macro had been used where _TO_ was intended
