[SPARC64]: Fix hypervisor TLB operation error reporting.
1) Trap level wasn't being passed down properly, we need to move it from %l4 into the correct outgoing arg register. 2) Although the TPC often provides the most direct clue, we have the caller PC so we should provide that as well. Signed-off-by: David S. Miller <davem@davemloft.net>
