[IA64] polish comments for tlb fault handler in ivt.S

Polish the comments specifically in vhpt_miss and nested_dtlb_miss
handlers.  I think it's better to explicitly name each page table
level with its name instead of numerically name them.  i.e., use
pgd, pud, pmd, and pte instead of referring as L1, L2, L3 etc.
Along the line, remove some magic number in the comments like:
"PTA + (((IFA(61,63) << 7) | IFA(33,39))*8)".  No code change at
all, pure comment update.  Feel free to shoot anything you have,
darts or tomahawk cruise missile.  I will duck behind a bunker ;-)
