xfs: turn the XFS_DA_OP_REPLACE checks in xfs_attr_shortform_addname into asserts

Since commit deed9512872d ("xfs: Check for -ENOATTR or -EEXIST"), the
high-level attr code does a lookup for any attr we're trying to set,
and does the checks to handle the create vs replace cases, which thus
never hit the low-level attr code.

Turn the checks in xfs_attr_shortform_addname as they must never trip.
