The former didn't protect the registers so it was trivially possible for a sync command and i/o command to fight each other and confuse the controller. Make the sync fib alloc/release functions inline and remove the somewhat worthless AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track this down in RELENG_4. END
