Subject: [PATCH] mdadm: output info more precisely when change bitmap to none

WHen change bitmap to none, the infos could be more accurate
based on existed bitmap 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 presented.
