md-bitmap: create and destroy wb_info_pool with the change of bitmap
The write-behind attribute is part of bitmap, since bitmap
can be added/removed dynamically with the following.
1. mdadm --grow /dev/md0 --bitmap=none
2. mdadm --grow /dev/md0 --bitmap=internal --write-behind
So we need to destroy wb_info_pool in md_bitmap_destroy,
and create the pool before load bitmap.
