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.
