Fix erroneous error reports about unbind failure
On platforms where binding of schedulers is not supported, numerous error
reports on the form "Scheduler <N> failed to unbind from cpu -1: enotsup"
were erroneously issued. This bug was introduced in the 'dev' branch
before R14B (commit 1b273b618002d65159453fdfb9520a9476e4423a). That is,
the bug has never been seen in a released runtime system.
