block: Fix io_context leak after clone with CLONE_IO
commit 61cc74fbb87af6aa551a06a370590c9bc07e29d9 upstream
With CLONE_IO, copy_io() increments both ioc->refcount and ioc->nr_tasks.
However exit_io_context() only decrements ioc->refcount if ioc->nr_tasks
reaches 0.
Always call put_io_context() in exit_io_context().
