block: ioc_task_link() can't fail
ioc_task_link() is used to share %current's ioc on clone. If
%current->io_context is set, %current is guaranteed to have refcount
on the ioc and, thus, ioc_task_link() can't fail.
Replace error checking in ioc_task_link() with WARN_ON_ONCE() and make
it just increment refcount and nr_tasks.
-v2: Description typo fix (Vivek).
