Don't allow thread_pool locking to be set by ASIO_CONCURRENCY_HINT_ macros.

Browse Source 
Conservatively prevent the thread_pool's internal locking behaviour from
being changed via the ASIO_CONCURRENCY_HINT_ macros, as there is no way
to use a thread_pool object in a purely single-threaded use case anyway.
This change also fixes a conversion warning.
