xfs: introduce directory geometry structure
The directory code has a dependency on the struct xfs_mount to supply the directory block geometry. Block size, block log size, and other parameters are pre-caclulated in the struct xfs_mount or access directly from the superblock embedded in the struct xfs_mount. Extract all of this geometry information out of the struct xfs_mount and superblock and place it into a new struct xfs_da_geometry defined by the directory code. Allocate and initialise it at mount time, and attach it to the struct xfs_mount so it canbe passed back into the directory code appropriately rather than using the struct xfs_mount.
