md: Avoid namespace collision with bitmap API
commit e64e4018d572710c44f42c923d4ac059f0a23320 upstream.
bitmap API (include/linux/bitmap.h) has 'bitmap' prefix for its methods.
On the other hand MD bitmap API is special case.
Adding 'md' prefix to it to avoid name space collision.
No functional changes intended.
