Remove bogus warnings from man page.

LANG=C man --warnings -l mdadm.8 > /dev/null

complains that '.XX' is an invalid macro.
This is not correct.  The sequence

   .ig XX
   anything can go here
   .XX

is correct and is ignored (see 'info groff' and the 'ig' index
entry).

However the same can be achieved with
   .ig
   anything can go there
   ..

and this produces no warnings, so use that instead.
