This commit replaces the macro XFS_DFORK_NEXTENTS() with the helper function xfs_dfork_nextents(). As of this commit, xfs_dfork_nextents() returns the same value as XFS_DFORK_NEXTENTS(). A future commit which extends inode's extent counter fields will add more logic to this helper. This commit also replaces direct accesses to xfs_dinode->di_[a]nextents with calls to xfs_dfork_nextents(). No functional changes have been made.
