mdadm: do not display bitmap info if it is cleared

"mdadm -X DISK" is used to report information about a bitmap
file, it is better to not display all the related infos if
bitmap is cleared with "--bitmap=none" under grow mode.

To do that, the locate_bitmap is changed a little to have a
return value based on MD_FEATURE_BITMAP_OFFSET.
