When invalidating an attribute leaf block block, there might be
remote attributes that it points to. With the recent rework of the
remote attribute format, we have to make sure we calculate the
length of the attribute correctly. We aren't doing that in
xfs_attr3_leaf_inactive(), so fix it.

I scratched my head reading:

in xfs_attr_leaf.h:
/*
 * Used to keep a list of "remote value" extents when unlinking an inode.
 */
typedef struct xfs_attr_inactive_list {
	xfs_dablk_t	valueblk;	/* block number of value bytes */
	int		valuelen;	/* number of bytes in value */
						     ^^^^^
						     |||||
} xfs_attr_inactive_list_t;

Where "valuelen" is clearly being used as blocks. A more obvious name is
the former "valueblk". Blame commit d7929ff6 for the confusion. Should change
the comment and/or variable one of these days ...
