md/md-bitmap: hold 'reconfig_mutex' in backlog_store()
Several reasons why 'reconfig_mutex' should be held:
1) rdev_for_each() is not safe to be called without the lock, because
rdev can be removed concurrently.
2) mddev_destroy_serial_pool() and mddev_create_serial_pool() should not
be called concurrently.
3) mddev_suspend() from mddev_destroy/create_serial_pool() should be
protected by the lock.
Fixes: 10c92fca636e ("md-bitmap: create and destroy wb_info_pool with the change of backlog")
