[XFS] kill BMAPI_DEVICE
There is no reason to go into the iomap machinery just to get the right block device for an inode. Instead look at the realtime flag in the inode and grab the right device from the mount structure. I created a new helper, xfs_find_bdev_for_inode instead of opencoding it because I plan to use it in other places in the future.
