[C API] GEOSCoordSeq_setOrdinate no longer returns error code

[jorisvandenbossche]

When trying to set an ordinate for a non-existing dimension, the C function no longer returns the correct error return value.

See ​https://github.com/pygeos/pygeos/issues/233#issuecomment-723860368 for context

This seems to stem from a small mistake in the refactor in ​https://github.com/libgeos/geos/commit/8e29f768e6d8597a5568acd628712583506f9928, which accidentally changed the error return value for GEOSCoordSeq_setOrdinate_r from 0 to 1, so we no longer catch the error. I further checked the rest of the file, but I think this is the only case of a wrong return code.
