In the pile of MIPS patches I really need to get around to submitting
(sorry!) I did this via avoiding the call to find_proc_desc from
mips_init_extra_frame_info.  I think that's functionally equivalent, so
this looks good to me (although Andrew's the one that needs to approve
it of course).

I also short-circuited the rest of mips_init_extra_frame_info if
PC_IN_CALL_DUMMY but that's a noop given the control flow in that
function if proc_desc is NULL.
