John Polstra 7e4977c94e Fix two bugs in the fault handler for copy{in,out} and friends.
First, it was failing to reset the PCB's pcb_onfault member to NULL.
Under some really obscure circumstances this might cause a wild jump
within the kernel when a panic would otherwise occur.  Second, the
handler was loading the GP register needlessly and with an incorrect
value.
