sapi: SMP support for chains
Add ISR lock to chain control for proper SMP protection. Replace
rtems_chain_extract() with rtems_chain_explicit_extract() and
rtems_chain_insert() with rtems_chain_explicit_insert() on SMP
configurations. Use rtems_chain_explicit_extract() and
rtems_chain_explicit_insert() to provide SMP support.
