Subject[PATCH 001 of 8] md/bitmap: Fix online removal of file-backed bitmaps

When "mdadm --grow /dev/mdX --bitmap=none" is used to remove
a filebacked bitmap, the bitmap was disconnected from the array,
but the file wasn't closed (until the array was stopped).

The file also wasn't closed if adding the bitmap file failed.
