pgsql: Fix incorrect return value in JSON equality function forscalars

Fix incorrect return value in JSON equality function for scalars

equalsJsonbScalarValue() uses a boolean as return type, however for one
code path -1 gets returned, which is confusing.  The origin of the
confusion is visibly that this code got copy-pasted from
compareJsonbScalarValue() since it has been introduced in d1d50bf.

No backpatch, as this is only cosmetic.
