[PATCH 2/2] mdadm: output info more precisely when change bitmap

[Guoqing Jiang <gqjiang@suse.com>]

When change bitmap to none, the infos could be more accurate
based on existed state type.

And s->bitmap_file is passed from cmd "--bitmap=TYPE", so remove
s->bitmap_file from err info since it should means change the
bitmap to one type failed rather than the type is already present.
