sapi: SMP support for chains

Browse Source 
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.
