x86/dumpstack: Make stack name tags more comprehensible

NMI stack dumps are bracketed by the following tags:

  <NMI>
  ...
  <EOE>

The ending tag is kind of confusing if you don't already know what "EOE"
means (end of exception).  The same ending tag is also used to mark the
end of all other exceptions' stacks.  For example:

  <#DF>
  ...
  <EOE>

And similarly, "EOI" is used as the ending tag for interrupts:

  <IRQ>
  ...
  <EOI>

Change the tags to be more comprehensible by making them symmetrical and
more XML-esque:

  <NMI>
  ...
  </NMI>

  <#DF>
  ...
  </#DF>

  <IRQ>
  ...
  </IRQ>
