fuse: refactor duplicate queue teardown operation

Browse Source 
Extract common queue iteration and teardown logic into
fuse_uring_teardown_all_queues() helper function to eliminate code
duplication between fuse_uring_async_stop_queues() and
fuse_uring_stop_queues().

This is a pure refactoring with no functional changes, intended to
improve maintainability.
