xfs: add a bests pointer to struct xfs_dir3_icfree_hdr
All but two callers of the ->free_bests_p dir operation already have a
struct xfs_dir3_icfree_hdr from a previous call to
xfs_dir2_free_hdr_from_disk at hand. Add a pointer to the bests to
struct xfs_dir3_icfree_hdr to clean up this pattern. To optimize this
pattern, pass the struct xfs_dir3_icfree_hdr to xfs_dir2_free_log_bests
instead of recalculating the pointer there.
