Remove an incorrect store of the SP when displaying information about a 

ktlbmiss on the kernel stack.  It was showing the temporary SP, not the
original SP.

Add a display of the first few wired entries of the TLB so when the ktblmiss
occurs, the TLB entries mapping the kernel stack can be verified.
