btrfs: introduce item_nr token variant helpers

The last remaining place where we have the pattern of

	item = btrfs_item_nr(slot)
	<do something with the item>

are the token helpers.  Handle this by introducing token helpers that
will do the btrfs_item_nr() work inside of the helper itself, and then
convert all users of the btrfs_item token helpers to the new _nr()
variants.
