[PATCH 3/8] do_md_run(): Fix misleading error message.

[Andre Noll]

In case pers->run() succeeds but creating the bitmap fails, we
print an error message stating that pers->run() has failed.

Print this message only if pers->run() really failed.

Thanks. I
 - added "md: " to the start of the subject line
 - fixed the conflicts with the first patch against my current tree:
     I think I already fixed some of that indenting
 - dropped the last patch....  I don't have a clear justification,
   but I currently want to leave the 'mddev' parameter there to remind
   me to review the implementation as I might want to do something
   a bit different there ... not sure yet.

They are now in my "for-next" branch which can be viewed at

Thanks for including the changes so quickly.

I have some more patches which are also simple, but slighlty more
involved. I'll queue them up and send them to the list for review
later today.
