Tsuneo Saito 103dcbe581 SPARC64: fix fault status overwritten on nonfaulting load 
cpu_get_phys_page_nofault() calls get_physical_address() twice,
that results in overwriting the fault status in the SFSR.
We need this change in order for nonfaulting loads to raising MMU faults
as normal loads do.
Also removed the call to cpu_get_physical_page_desc() since we are
going to modify nonfaulting loads raising MMU faults.
