[PATCH v1 12/19] xfsprogs: Factor out xfs_attr_rmtval_remove_value

[Allison Collins <allison.henderson@xxxxxxxxxx>]

Because new delayed attribute routines cannot roll
transactions, we carve off the parts of
xfs_attr_rmtval_remove that we can use.  This will help to
reduce repetitive code later when we introduce delayed
attributes.
