[PATCH] md - 1 of 3 - Remove some inappropriate MD_BUG calls when hot_removing

[NeilBrown <neilb@cse.unsw.edu.au>]

Marcelo,
  This is the first of three patches for 2.4.21-pre that make smallish
  improvements to md/raid.
  Thanks, NeilBrown


If you try to hot-remove an active device, md will currently
print an MD_BUG message which is inappropriate and confusing.
This patch removes these.
